How to set a date in an apex class.

To set a date field to a fixed value in a Salesforce Apex class, you can use the newInstance(year, month, day) method from the Date class. The code looks like this:

Another option that is especially useful in Apex test classes, is setting the date relative to today’s date. This helps overcoming issues with validation rules for future/past dates, etc. This can be done using System.today() for date-fields and System.now() for datetime-fields. In code it would look like this:

Instead of using “ + 3 ” you can also utilize the addDays(additionalDays) method.

Why did I write about this?

Even if I usually focus on Salesforce Marketing Cloud and this is related to the core Salesforce platform, it is a question that is still asked a lot, which I can also see based on the activity there is on a rather old answer on Salesforce StackExchange I wrote a couple of years ago about setting dates in apex test classes.

To make sure this information can be easily found for the readers of my blog as well, I thought I’d add a short post about it 🙂

Apex: The DateTime Class & Fun With Time Zones

There is quite a bit of good information and resources out there on using the DateTime class in Salesforce. In fact, the Salesforce Apex Developer Guide itself has published  great examples on using this class .

However if there’s one thing I’ve learned over the past 5 years of professional development, it’s this: writing code using dates and time zones is a developer’s worst nightmare. From fixing unit tests on January 1st because a date was hardcoded and somehow made it past code review, to a client in another country complaining that something is broken because they told the system to exclude certain dates and it didn’t listen… I can’t possibly remember all of the stories I’ve heard.

So let’s take a deeper dive into the DateTime class with a few additional examples. Hopefully you’ll learn a thing or two – I know I have.

UTC vs. User’s Time Zone

Time zones are confusing. Salesforce makes this a little less confusing for you, but there’s still definitely room for error if you don’t know what all of the various DateTime methods are doing.

Salesforce stores all DateTime values in the database in UTC. When you’re viewing a record in Salesforce, the Created Date will be adjusted based on your time zone preferences. However, the UTC value is the value retrieved in Apex.

Lead testLead = new Lead(LastName = 'Tester', Company = 'Test Company'); insert testLead; testLead = [SELECT CreatedDate FROM Lead WHERE Id = :testLead.Id]; System.debug(testLead);

The above code will insert a dummy Lead record and then output the record, which includes the value of its CreatedDate. Regardless of the time zone you are in, the CreatedDate will be in UTC.

What if I want to know the time for the current user?

Given a DateTime, you can convert the instance into a string using the format() method, which will convert the DateTime into something like “2/3/2017 1:20 PM”. If a different output is desired, the format() method also accepts additional parameters so you can specify a different Java simple date format.

There are other methods that also output various components of the DateTime in the user’s time zone, like date() and time(). It’s important to read through the documentation to understand the value returned.

DateTime dt = DateTime.newInstance(2017,2,3,13,20,30); System.debug(dt.date()); // Returns Date: 2017-02-03 00:00:00 System.debug(dt.time()); // Returns Time: 13:20:30.000Z System.debug(dt.format()); // Returns String: 2/3/2017 1:20 PM System.debug(dt); // Returns UTC DateTime System.debug(DateTime.now()); // Returns UTC DateTime

newInstance vs newInstanceGmt

So, we just reviewed that the date() and time() methods return the Date and Time in the user’s time zone. Two other methods – aptly named dateGmt() and timeGmt() – return the Date and Time in the GMT time zone.

What if you need to construct a new DateTime instance from a given Date and a Time? Well, you’d better determine whether or not the Date and Time is in GMT or in your user’s current time zone, otherwise your results are not going to be as expected!

DateTime dt = DateTime.newInstance(2017,2,3,13,20,30); Date localDate = dt.date(); Time localTime = dt.time(); Date gmtDate = dt.dateGmt(); Time gmtTime = dt.timeGmt(); DateTime newDateTime1 = DateTime.newInstance(localDate, localTime); System.debug(newDateTime1); // Returns UTC DateTime as expected DateTime newDateTime2 = DateTime.newInstance(gmtDate, gmtTime); System.debug(newDateTime2); // Returns UTC DateTime + local time offset!

In this example, since I live 8 hours behind UTC time the output of newDateTime2 is 8 hours  ahead of UTC time. This is because I’m passing the Date and Time as GMT time into the newInstance method and the system is expecting me to pass in the user’s local time.

If I knew the date/time in GMT that I wanted, I would instead use the newInstanceGmt method:

DateTime dt = DateTime.newInstance(2017,2,3,13,20,30); Date gmtDate = dt.dateGmt(); Time gmtTime = dt.timeGmt(); DateTime gmtTime1 = DateTime.newInstanceGmt(gmtDate, gmtTime); System.debug(gmtTime1); // Returns UTC DateTime as expected DateTime gmtTime2 = DateTime.newInstanceGmt(2017,1,1,4,5,6); System.debug(gmtTime2); // Returns UTC DateTime: 2017-01-01 04:05:06

The DST Time Warp

Congratulations for making it this far! Let’s talk about time zones and Daylight Savings Time.

Many different parts of the world participate in Daylight Savings Time. In 2016, Daylights Savings Time ended for the United States on November 6th. This can have unintended consequences if you are manipulating DateTime instances in Apex code.

For example, let’s say that it is currently December 18th, 2016 and users are running your application that performs a process that filters out all records created this month or last month – so any records created after October 31st at 11:59:59pm in the user’s current time zone. (Yes – you can do this through SOQL – but let’s assume that SOQL is not possible for this use case.)

Because the system needs to do this calculation dynamically based on the current user and the current date, you might have been tempted to write Apex similar to the following:

Date today = Date.newInstance(2016, 12, 18); // To illustrate the problem, let's not use Date.today() DateTime beginningOfMonth = DateTime.newInstance(today.toStartOfMonth(), Time.newInstance(0,0,0,0)); DateTime brokenDateTimeFilter = beginningOfMonth.addMonths(-1).addSeconds(-1); System.debug(brokenDateTimeFilter); // My Result: 2016-11-01 07:59:59 System.debug(brokenDateTimeFilter.date()); // Result: 2016-11-01 00:00:00

Now, at first glance this DateTime might appear to be fine. (Note: the result of the debug statement on line 4 will be different for you depending on your time zone.) However, the result of line 5 should be somewhat baffling. Our DateTime instance should represent October 31st at 11:59:59pm in the user’s current time zone, yet the date() method (which returns a Date in the user’s local time) returns November 1st. What’s going on here?

Let’s first take a look at code that works:

Date today = Date.newInstance(2016, 12, 18); // To illustrate the problem, let's not use Date.today() DateTime dateTimeFilter = DateTime.newInstance(today.toStartOfMonth().addMonths(-1), Time.newInstance(0,0,0,0)); dateTimeFilter = dateTimeFilter.addSeconds(-1); System.debug(dateTimeFilter); // My Result: 2016-11-01 06:59:59 System.debug(dateTimeFilter.date()); // Result: 2016-10-31 00:00:00

When comparing the results of this code versus the other code you’ll notice that while it is similar, the first example produces a DateTime that is an hour later than in the second example.

So what happened: on November 6th, the user’s local time switched from Daylight Savings Time. However, simply adding months or days to an already constructed DateTime instance isn’t going to take Daylight Savings Time into consideration. There is nothing technically wrong with the first example – the code literally did what you told it to do.

In the second example, notice that we are only working with one DateTime instance.  Never manipulate a DateTime instance to switch it to another date. Instead, figure out the exact date that you want before constructing the DateTime instance.

Okay, okay. So I am at fault for breaking my own rule here, since I used the addSeconds method to subtract a second from the DateTime. This should be relatively safe to do, but a better approach would be:

Date today = Date.newInstance(2016, 12, 18); DateTime dateTimeFilter = DateTime.newInstance(today.toStartOfMonth().addMonths(-1).addDays(-1), Time.newInstance(23,59,59,0)); System.debug(dateTimeFilter); // My Result: 2016-11-01 06:59:59 System.debug(dateTimeFilter.date()); // Result: 2016-10-31 00:00:00

And now, your calculations will work as expected regardless of that annoying DST.

I hope you found these examples to be helpful. If you have any questions or suggestions after reading through this, please feel free to leave feedback as a comment below.

Until next time,

— Robert

Alter enters Apex Legends with new season launching May 7

Full breakdown on new Legend, the return of Solos Takeover, and more.

Things are about to get seriously chaotic in the newest season of Apex Legends. Starting May 7 Upheaval lives up to its name with plenty of new content and changes that’ll keep even the most seasoned Legends on their toes. Ready to find out what’s coming soon to the Apex Games? Just keep reading.

Embrace chaos

“Life’s just a game and lucky you, you’re playing it with me.”

Things are really heating up this season, and new Legend Alter is striking the match. There’s very little known about this new Void tech user except that calamity seems to follow in her wake. Is she the cause or simply in the wrong place at the wrong time? No one can say. But she does seem to take real joy in watching catastrophes unfold, and reveling in what chaos brings out in those around her. While her morality may be in question, her abilities definitely aren’t:

Gift from the Rift – Can remotely interact with a deathbox to claim one item. Cannot be armor.

Void Passage – Creates a portal passageway through a surface.

Void Nexus – Create a regroup point that all allies can remotely interact with to open a phase tunnel back to that location.

What brings the mysterious Alter to the Apex Games? No one can really say. But one thing’s for sure, when she’s around life is never boring.

Stand alone in Solos

Duos is out as Solos Takeover makes its much-anticipated return at the beginning of the season. This fan-favorite is back with enough new mechanics to keep things very interesting. It’s every Legend for themselves, which means no one will be watching your back – so you’ll need to rely on your Battle Sense to detect nearby enemies. Pre-kitted weapons and attachments will help you stay one step ahead of the competition, while Second Chance auto-heal will keep you in fighting shape long enough to come out on top. Drop into Solos Takeover starting May 7.

Broken Moon shatters

A lunar nightmare becomes reality as Olympus appears to crash into Cleo’s Stasis Array Node, reshaping the battlefield with new POIs and a streamlined map (including new rotations and revamped zip rails ripe for spreading havoc). Debris from the crash as well as meteor strikes and what some are calling unknown biological material have led to a lockdown and quarantine in what was the Promenade. Welcome instead to the Quarantine Zone.

If you’re looking for intense close-quarters action and fast-paced looting, this is where you’ll find it.

Breaker Wharf has shifted to where the Backup Atmostation was originally, and that’s not the only change you’ll have to look forward to. Raining debris has changed up the topography as well as playstyle options – upping the pandemonium potential. Space Port’s move should provide some choice loot opportunities, while Cliff Side offers up an interesting layout primed for intense tug-of-war battles between the high and low grounds. The new Lunar buildings of Solar Pods should keep things moving as well as offer up new combat experiences.

Need a moment to catch your breath? Underpass should give your team the breathing space you need to get back in the game. And Experimental Labs is a great spot for anyone looking for a little high-risk, high-reward action. Finally, new rotations round out the fun offering you a variety of opportunities to make life a little more difficult for opposing squads.

Chaos is coming

There’s even more on the way during Apex Legends: Upheaval, including the opportunity to slice in style with customizable Apex Artifacts, leaving your unique signature of destruction. Then corrupt your style with the Upheaval Battle Pass, unlocking 100+ rewards including Exotic Shards.

It’s a new world, Legend – get ready to disturb the peace.

New Updates Coming with Apex Legends™: Upheaval

Get insights into game updates coming in apex legends™: upheaval including solos, alter, and a new dawn of broken moon.

NEW UPDATES COMING WITH APEX LEGENDS™: UPHEAVAL

Want to watch the world burn, Legends? Get ready to disturb the peace, because upheaval is upon us! 

Bend the world with Alter and her Void-based abilities, then sow chaos in Solos Takeover—with kitted guns and new ways to dodge (and deal) death. Descend into a new age of Broken Moon, unearthing new POIs and faster paths to mayhem. More fights? That just means more opportunities to slice in style with the latest customizable Apex Artifacts. It’s time to sew mayhem across the Outlands, so let’s get to it!

TAKEOVER: SOLOS

Well, well, well…looks like Solos is coming back after all! Replacing Duos from the beginning of the season, take on the Outlands by yourself in this revamped variant. We’ve taken aspects of some of our most popular modes and integrated them to keep things interesting: use your Battle Sense to detect nearby enemies, tear things up with pre-kitted weapons and attachments, and keep the fight going with auto heal and Second Chance mechanics. We get it–sometimes you want to drop hot and heavy without having to carry the squad. It’s every Legend for themselves…for now. Solos Takeover is live May 7, 2024 to June 24, 2024.

NEW LEGEND: ALTER

When Alter emerged from her dimension into another with her past held close to the chest, she had only two things: her interdimensional traveling Void tech, and a desire to have fun. She did what she wanted when she wanted, never needing to stick around for the consequences of her actions. Morality and responsibility were things of the past as Alter traveled throughout different realities, drawn to worlds on the edge of complete destruction. 

Whether something devastating was already happening or she helped usher in the apocalypse herself, Alter was always there to watch whatever catastrophe ensued. She loved seeing worlds end and seeing the true nature of the people come out within the chaos. However, in some ruined dimensions, there was a common denominator that intrigued her–one that would lead her to witness the grandest apocalypse of all. Seeking out the next world it would condemn, Alter has landed in ours, ready to do what’s necessary to see her wish fulfilled.

PASSIVE: GIFT FROM THE RIFT

Alter can see and remotely interact with nearby death boxes to claim a single item. While she cannot take shield cores through the void, any other prize can be snatched from afar.

TACTICAL: VOID PASSAGE

Alter fires a void blast from her tail that shatters against a surface to open a dimensional gateway through from one side to the other for a short time. Crossing through the portal is instantaneous, and can be done from either direction, but travelers will remain phased briefly after exiting. 

The angle of this shot determines what surface the exit will open on and can be used to open passages through ceilings and ledges, allowing Alter to place her passages creatively through the environment.

ULTIMATE: VOID NEXUS

Alter can deploy a Void Nexus that allies can remotely interact with to open a phase tunnel back to that point. When a tunnel is opened, that player will phase walk from their location to the Void Nexus and leave behind a portal that any player can follow through. The Nexus can be used even while downed, and it is an incredible way for Alter and her squad to regroup to a position of power for a reset, provided interlopers do not pursue…

APEX ARTIFACTS

The pantheon of Apex Artifacts is expanding. Check out our dedicated blog for all things Apex Artifacts including lore connections and customizations.

MAP UPDATE: BROKEN MOON

Our goals for the Upheaval update were to bring a new combat experience throughout Broken Moon and within the new POIs, while also changing the identity of the map. Detached and now floating in outer space between Cleo and Boreas, the colony of Hope is forever changed. The Terraformer has had to recalculate and adapt which has, in turn, mutated familiar biomes and created an exotic landscape.

POINTS OF INTEREST

Quarantine zone.

Where Promenade East met West is now the Quarantine Zone. Promenade was wiped out by the Stasis Array Node that crashed down to the map. When what appeared to be Olympus collided with the Stasis Net satellite, Broken Moon’s protection was no longer—allowing the crash debris and meteors to rain down along with unknown biological material that has required the area to be quarantined.

From a game design perspective, the goal was to deliver a faster-paced and more deliberate combat experience. We condensed the whole center of the map, making it more predictable where players can and cannot rotate from. The layout of this POI makes for fast pace looting, combat, and some fun action with the covered ziprail loop, while also providing a safe rotation from teams at the lower end.

BREAKER WHARF

Breaker Wharf was also affected by the debris raining down, which gave us some room to play. Because this POI was so secluded from the rest, we felt that there was an opportunity to move it – and move it did! Now, look out for it where the Backup Atmostation was.

This design change is one that aims to break up the playstyle of this side of the map, where there were a lot of science buildings that played in a similar manner. Bringing over a more industrial kit will help break that repetitiveness, offering more gameplay variety to players.

Space Port is a smaller POI that breaks the mold of the original larger POIs and sits in the area that once was Breaker Wharf (recreated by the mobilization to help keep Broken Moon alive and together). It serves a bigger purpose to bring more action to spaces less-traveled, and is the perfect drop for one team to get some good loot.

Cliff Side sits in-between the Quarantine Zone and Stasis Array, and is another smaller POI with an interesting X layout allowing for a tug-of-war between the high and low grounds. Its placement also allows for less of a hike to rotate and it’s a great spot to strategize during your next rotation.

Solar Pods utilizes the new Lunar buildings to introduce the bridge between Foundry and Cultivation as a new POI. The intent of this placement is to speed up the pacing of the map between POIs and offer a new combat experience within them.

Underpass is another one of the smaller POIs that allow for a slower paced beginning for teams looking for less of a hot drop. This POI also sticks to the high-level goal of speeding the pacing up while allowing for more desirable rotations.

EXPERIMENTAL LABS

Experimental Labs was an addition to a camp that existed and allowed for more loot in a less-than-desirable landing location. Looking for some fun rooftop to rooftop combat? This is your drop.

NEW ROTATIONS

What would an Apex Legends map update be without some fresh and updated rotations? Here are a few that you may want to be aware of to avoid getting pinched…

Hazmat Tunnel is a new rotation that connects Quarantine Zone and Terraformer for a risky, but rewarding rotation. Offering speed and more loot, it’s up to you to decide how long is too long to stick around. This tension point should allow for some fun and interesting conflict.

This rotation between Terraformer and Stasis is a nice anchor point and the perfect spot for strategy planning while avoiding difficult chokes.

Connecting Cultivation, Terraformer, and Quarantine Zone, this area has multiple power positions with interesting ways to attack each of them.

Between Quarantine Zone and Underpass, this quick rotation has some fun slide downs and links to a covered bridge.

Use the space between Space Port and Perpetual Core to avoid being caught thanks to multiple rotation opportunities.

This rotation connects Perpetual Core and Quarantine Zone, offering some fun platform to platform combat. 

The team had a lot of fun putting this update together and we hope you enjoy the galactic effort. There are also some smaller quality of life details that have been improved upon as well, but we’ll leave those for you to discover.

SEE YOU ON THE DROPSHIP

With Broken Moon rising from the rubble, the long awaited return of Solos, a fresh pantheon of Apex Artifacts, and a brand new Legend, this season is just beginning. Strap in, Legends, who knows what will awaken when peace is disturbed. One more time with feeling: the upheaval is upon us.

Apex Legends Season 21: Upheaval Update & Patch Notes

Apex Legends Season 21: Upheaval launches this week, and developer Respawn Entertainment has released the patch notes for Tuesday, May 7's seasonal update, which is now live.

From a brand-new Legend and map makeover to weapon tweaks and updates for older Legends' abilities, the Season 21 update has it all. Keep scrolling for a closer look at every change that hit Apex Legends as part of Upheaval, and then check out everything in the Apex Season 21 battle pass .

New Legend: Alter

Alter holds her cards close to the chest when it comes to her past , and is, by Respawn's own admission, an unreliable narrator. However, the Apex Legends developer has been transparent when it comes to what she's capable of on the battlefield .

Alter's abilities and Legend Upgrades are as follows:

• Passive: Gift From The Rift--Alter can remotely interact with a deathbox to claim one item. (This item cannot be a Shield Core.)
• Tactical: Void Passage--Alter creates a portal passageway through a surface.
• Ultimate: Void Nexus--Alter creates a regroup point that all allies can remotely interact with to open a phase tunnel back to that location.

When it comes to Legend Upgrades, Alter can select one of two upgrades upon reaching Level 2 (Rare-tier Shield Core), and has two more to choose from when she hits Level 3 (Epic-tier Shield Core).

Level 2 Upgrades:

• Ultimate Cooldown: Reduce Void Nexus cooldown by 30 seconds
• Void Vision: Extend highlights and see health bars after exiting Void Passage.

Level 3 Upgrades:

• Eternal Nexus: Void Nexus never times out.
• Tactical Cooldown: Reduce Void Passage cooldown by 10 seconds.

Solos Takeover

Respawn has previously stated that Solos Mode would never return to Apex, it seems that Respawn's stance on the issue has changed, as Solos Mode will be replacing Duos Mode for the first half of Season 21, from starting on May 7 and ending on June 24.

"We’ve taken aspects of some of our most popular modes and integrated them to keep things interesting: use your Battle Sense to detect nearby enemies, tear things up with pre-kitted weapons and attachments, and keep the fight going with auto heal and Second Chance mechanics," Respawn said of the changes made to Solos Mode ahead of its reintroduction to the game.

Upheaval map rotation

It's taken a quite a while , but Apex's Broken Moon map is finally getting an update, including tweaks to improve rotations, address loot deserts, and generally make the map a less frustrating one to for players to engage with. Of course, Broken Moon won't be the only playable map available this season. Season 21's map rotation is listed below:

• Broken Moon
• Kings Canyon
• World's Edge

This rotation applies to both Ranked Mode and Pubs, but the Season 21 patch notes suggest the map rotation will change after the first half of the season.

Updated Apex Artifacts and a new in-game currency

Apex Artifacts are getting some serious upgrades after the introduction of the Katar in Season 21. These Heirloom Weapon -like melee cosmetics now have a whole host of customization options. Regarding the changes, Respawn says, "Apex Artifacts were given to each of the Legends by the Mercenary Syndicate to bring something new and exciting to the Games to distract from the recent disruption of Revenant and untimely death of Duardo Silva. The smallest particle of Branthium indefinitely powers each Katar in order to maintain their ominous presence. With the assistance (and insistence) of Rampart herself, the Katars were created with the ability to be modded for customization to each wielder’s preference—that means you . The Legends have their heirlooms, and now you have something that’s yours."

The Katar now has six variants, each with five customization options. Each customization option must be unlocked in order (first the Base, then the Theme, then the Power Source, then the Activation Emote, and finally, the Deathbox). Customizations can be purchased via a new kind of currency called Exotic Shards, which can be purchased directly, unlike the Heirloom Shards that allow players to unlock Heirloom Weapons and Prestige Skins. Exotic Shards can also be found in small amounts throughout the Upheaval battle pass. For more information on Apex Artifacts and the Katar, check out Respawn's blog post on the new melee weapon.

Weapon changes

When it comes to Care Package weapons, Season 21 will see the Wingman return to the standard loot pool, with its care package buffs removed. Damage will be reduced from 50 to 45, projectiles will be reduced to their pre-Care-Package size, the Skullpiercer Elite hop-up will be removed (though the weapon will instead be able to equip the Boosted Loader hop-up), hipfire accuracy will be reduced, and magazines can no longer be used as an attachment.

The Devotion will take the Wingman's place in the Care Package, and receive the following buffs:

• New Reverse Hipfire: Sustained hipfire will tighten accuracy instead of widen it.
• Damage increased from 15 to 16
• Magazine size increased from 48 (with an Epic-tier magazine) to 54
• Reserve Ammo: 324
• Empty reload time significantly reduced

The Nemesis , Triple-Take, Peacekeeper, Prowler, and Longbow will be getting the gold weapon treatment this season, and a new feature meant to make early-game encounters a bit less frantic has been introduced: The first Supply Bin opened by an unarmed player is guaranteed to contain a weapon. Additionally, Survival Items will now only spawn in Support Supply Bins when the squad is in need of them.

Legend changes

Lots of Legends are getting their abilities tweaked and reworked this season, but Newcastle's abilities are getting some of the biggest changes. As of Season 21, the throw animation for his Mobile Shield ability will be sped up, making it 2.5 times as fast as it previously was. But the biggest changes affect his Castle Wall ultimate ability. While energized, the Castle Wall will now block both bullets and ordnance, but only if they're thrown directly at the Castle Wall. Projectiles and ordnance being thrown from the opposite side of the wall will still hit, and the upgrade will also not prevent aerial bombardments from Legends like Bangalore and Gibraltar. The Castle Wall will also stay energized 50% longer than it has in the past (1 minute rather than 30 seconds). Newcastle's Stronghold Legend Upgrade has also been buffed, and will increase Castle Wall's energized status to 3 minutes rather than the previous 2.5 minutes.

As for the other Legends, Catalyst is also getting some big changes in Season 21. Her Piercing Spikes cooldown has been decreased from 25 seconds to 20 seconds, and her Long Cast Legend Upgrade has been integrated into her Tactical Piercing Spikes ability be default. Her Dark Veil ultimate ability has also been buffed, and is now 45 meters long instead of 40 meters long. As for upgrades, Long Veil has been moved to Level 2, and since Long Cast has been integrated into the base version of her Tactical, a new Legend Upgrade called Ferro-Door is replacing it. Ferro-Door allows Catalyst to fully rebuild and reinforce missing doors with her passive ability.

Upheaval battle pass

The Upheaval battle pass won't be available to investigate fully until Season 21 goes live, but from what we've seen of it , the battle pass includes void-themed skins for various Legends, including Caustic. As previously mentioned, the battle pass will also include a new type of currency: Exotic Shards, which can be used to purchase upgrades for players' Apex Artifacts.

Full patch notes

Apex Legends Season 21: Upheaval launches on Tuesday, May 7 at 10 AM PT / 1 PM ET. The Upheaval patch notes are listed in full below:

PATCH NOTES

Balance updates.

Care Package

• Projectile size reduced to pre-care package values
• Damage reduced to 45 (was 50)
• Skullpiercer Elite removed
• Hipfire accuracy reduced
• Now takes Boosted Loader Hop-Up
• No longer takes magazines as an attachment
• NEW Reverse Hipfire: sustained hipfire will tighten accuracy instead of widen
• Damage increased to 16 (was 15)
• Magazine size increased to 54 (was 48 at purple)

Gold Weapons Rotation

• Nemesis Burst AR, Triple-Take, Peacekeeper, Prowler PDW, Longbow DMR

Guaranteed Weapons out of Loot Bins

• The first loot bin opened by an unarmed player will always contain a weapon

Dev Note: Bringing knuckles to a gunfight isn’t the most engaging gameplay, so we’re improving weapon acquisition consistency in the early game. When completely unarmed, opening a bin will guarantee at least a low tier weapon.

Retrieving Banners from Death Boxes

• Running, shooting, punching and reviving will all break out of the banner collect animation while still registering as a successful collection
• Players can immediately interact with a Death Box a second time while the animation is playing or continue holding the interact button to collect and enter a Death Box in one flow

Dev Note: It’s happening, it’s finally happening! I’ve died, you’ve died, we’ve all died trying to help our allies get back in the fight, but at least now we can’t blame grabbing the banner! Collecting banners is a positive action in Apex and for too long we’ve punished that action with a brief moment of pure helplessness. We’re putting your gun quite literally back in your hands, so get out there and save some Octanes and Wraiths!

Survival Items + Support Bins

• Survival items now only spawn from a support bin’s tray if the team is in need

Dev Note: Survival items have been feeling abundant lately so we’re reducing their frequency in support bins by only spawning them when players meet specific requirements (like needing a Mobile Respawn Beacon when you’ve got eliminated allies)

WEAPONS & ATTACHMENTS

30-30 Repeater

• Skullpiercer Hop-Up removed

Dev Note: The 30-30 has been dominating the mid-long range for a few seasons and our recent adjustments weren’t quite enough to dethrone it. Removing the Skullpiercer should create some space for other Marksman and Sniper rifles to shine.

Charge Rifle

• ADS recoil improved and stabilized

Dev Note: The Charge Rifle remains a high risk-reward weapon, however the risk slightly outweighs the reward. We’ve taken a smoothing pass at its recoil so it shouldn’t be quite so unwieldy when firing.

Longbow DMR

• Barrel Stabilizer attachment removed
• Base recoil significantly improved
• Projectile gravity reduced
• ADS in and out time reduced

Dev Note: We’ve always considered the Longbow a great entry level sniper that’s easy to run. Over time, we’ve come to realize that being a good entry level weapon and requiring lots of attachments to come online are at odds with one another. Simplifying the Longbow’s loot chase to make it more base level approachable is intended to improve its early game effectiveness and overall consistency as a sniper.

Triple-Take

Dev Note: The Triple-Take is a strong weapon on paper, but it can feel a bit sluggish to maximize damage output. Providing quick reloads and extra ammo in the mag allows players to keep pressuring for longer with more chances to punish.

• Skullpiercer removed from the loot pool
• Reloading while near empty will speed up reloading and overload the next magazine with extra rounds

1x Digital Threat Optic

• Removed from loot pool and all locked set weapons

Dev Note: The Digi represents a sharp power spike in Apex—a single loot item that both counters and synergies with a specific Legend. Its power ebbs and flows with the Legend meta in a way that proves very difficult to tune. We’re giving the 1x Digi a hiatus while we investigate healthier optic based perks.

• Changed to left-hand cast
• No longer stows weapons or interrupts consumable use when launching
• Phase Breach: inspired by some Alter tech, nearby enemies will be highlighted for players traveling through the Void

Dev Note : It’s about time, huh? Allowing Ash to fire her Arc Snare with her off-hand has been something we’ve wanted to do for a while now. Holstering and redrawing her weapon to use the snare put Ash at a disadvantage in combat and minimized a lot of her play options. Ash should now be able to be much more active with her snare and apply pressure more aggressively when successful.

• Whistler: damage from a planted smart bullet increased to 10 (was 5)
• Care Package Insight: removed
• NEW Sling-Shot: improves Ballistic’s base sling weapon to a blueset at Level 2 and a purpleset at Level 3

Dev Note: We’re replacing a lackluster perk with something more interesting, especially for those Ballistic players that like tapping into their sling weapons in non-Ult scenarios. Three Tac related upgrades is plenty, let’s make some room for that third weapon.

• Cooldown increased to 4m (was 3m)
• Knocks with Ult active no longer extend duration
• Tactical Cooldown: removed
• Taste of Blood: buffed HP gain on knock to 50 (was 25)
• NEW Long Hunt: knocks extend Beast of the Hunt duration

Dev Note: Beast of the Hunt has a lot of power baked into it considering perfect vision through smoke, increased move speed, and a generous extension timer. We wanted to break that down to see if players lean into a specific playstyle and ax the uninteresting hidden power of a decreased Tac cooldown. Bloodhound synergizes very well with two of the most popular Legends at the comp level, but we want to be mindful of their appeal across skill bands. We’re not doing anything big to this approachable Legend until we gauge their place at the top-end in a digi free world.

• Cooldown decreased to 20s (was 25s)
• Long Cast upgrade integrated into base Tactical
• Dark Veil length increased to 45m (was 40m)
• Long Cast: removed
• Long Veil: moved to Level 2
• NEW Ferro-Door: fully rebuild and reinforce missing doors with Passive.

Dev Note : Catalyst could use some love after her Ult nerfs, and Sister Spikes needed some competition. Hopefully making Tac charges more available with a baseline cooldown buff and creating a situationally strong alternative via passive upgrade helps strike a balance. Now that the Ult upgrades are decoupled, there are some difficult choices to make at both levels that we suspect are influenced by match flow. Will you hunker down with a friendly zone pull, or will you need an upgraded wall to help with rotations?

• Gas damage and slow now stops immediately after Caustic's squad is eliminated
• Gas damage ramps from 4 → 10 max (was 5 → uncapped), damage on knocked players down to flat 4 (was 5)
• Can no longer target a Revenant while Forged Shadows is active
• When Revenant activates Forged Shadows, any temporary shield generation ends immediately. Revenant will keep any temporary shields generated before activating his Ultimate.
• Battery Collection: removed
• NEW Battpack: can stack up to 3 Shield Batteries per inventory slot (doesn’t stack with Gold Backpack)

Dev Note : Conduit maintains a healthy pick rate and has cemented herself as a strong Support pick even after her last round of nerfs. We don’t want to hit her effectiveness as a Legend that pushes the tempo in combat. This is a targeted nerf to one of her synergies that felt more exploitable than we’d like.

• Network Traffic upgrade now integrated into base kit
• Squadcount banners are now visible anytime the drone is in a deployed state
• Tac & Ultimate Cooldowns: removed
• Network Expansion: moved to Level 2
• NEW Quick Ping: improved drone handling (faster accel/decel)
• NEW Satellite Imagery: drone scan persists for an additional 1.5s
• NEW Hackathon: cut the drone cooldown in half, gain a speed boost anytime he uses his Ult or the drone is destroyed

Dev Note : Crypto’s upgrades at the start of Season 20 left a lot to be desired. We hope this suite of changes resonates with a couple different playstyle types—particularly when it comes to players’ affinity to pilot the drone more actively vs. passively.

• Big Bang: removed
• NEW Ring Master: gain access to Ring Consoles
• Simplified and buffed damage mitigation to remove lingering burn effects
• Take a flat 20 damage when crossing The Motherlode instead of 37 (50% of 75 hp) over time
• Wreckless: fixed explosive damage mitigation not being applied on continuous Knuckle Cluster hits (should only take about 32 damage from a full Knuckle Cluster now with Wreckless)

Dev Note : Fuse is destruction and chaos. The goal of these changes, whether it be a new strategic-level upgrade or a simplification of a convoluted damage model, is to bring some method to the madness.

• Mobile Shield: throw anim speed increased (~2.5x faster)
• Will now destroy incoming projectiles headed towards the front of the wall while energized. It will not destroy projectiles fired from behind the wall nor bombardments from other Legend’s Ultimate projectiles.
• Castle Wall energized duration increased to 1m (was 30s)
• Upgrade - Stronghold: increased energized duration to 3m (was 2.5m)

Dev Note : The Castle Wall’s in-game strength rarely matches the grandeur of its presentation. More often than not, the wall serves as a grenade beacon to surrounding threats knowing that Newcastle just jumped to an ally in distress. An Ultimate-level wall should not fail as much as it does, especially on a Support Legend that’s built around turning the tide when his squad starts losing the advantage. The wall now requires more calculated counterplay and makes the Stronghold upgrade a more compelling option. We were also finding the long wind-up when tossing his Mobile Shield left him pretty vulnerable trying to get back to his weapon, so we’ve sped up the animation to let him be more reactive with it.

• Wreckless: removed
• Mad Hops moved to Level 2
• Thick Skin: now Level 2 and 3, updated to take 5 less Stim damage to reflect that it can be selected twice (was -25%)

Dev Note : Octane has a “Plus Ultra'' tattoo, so we shouldn’t inhibit his ability to double down on his tac or ult. While Wreckless was thematically fun, Octane already has one of the best forms of explosive damage mitigation that’s less hidden: stim away.

• Falling Stars: Pylons will stop spawning Arc Stars when her squad is eliminated
• Split Circuit: no longer reduces shield regen capacity
• Into the Void and Dimensional Rift: nearby enemies will be highlighted for players traveling through the Void
• New POIs: Cliff Side, Experimental Labs, Solar Pods, Space Port, Quarantine Zone, Underpass
• Breaker Wharf updated
• New rotations to switch things up and keep squads on the move
• Added possible Ring Console spawn locations to Mirage à Trois and Survey Camp
• Added possible Survey Beacon spawn locations to Survey Camp and The Geyser
• Added possible Crafter spawn location to Command Center
• Added possible Survey Beacon spawn locations to The Wall, and the unnamed POIs Northeast of Checkpoint and at the edge of the map East of Storm Catcher
• Six week Duos takeover
• Automatically respawn once if you die in the first 4 rounds
• Second chance converted to EVO if unused by the round cutoff
• Battle Sense: HUD indicator when enemies are within 50 meters
• Health regenerates out of combat
• Auto heal starts after each kill
• Additional adjustments to loot pool, circle sizes, and round times to accommodate solo play
• Lockdown added to rotation: Zeus Station, Monument
• Control: Production Yard, Thunderdome
• Gun Run: The Core, Wattson's Pylon
• Lockdown: Monument, Zeus Station

• Control: Barometer
• Gun Run: Wattson’s Pylon
• Lockdown: Zeus Station
• TDM: Zeus Station
• Control: Barometer, Caustic Treatment
• Scorelimit: 35
• Time Limit: 10 minutes
• Increased health regen
• Skull Town, Zeus Station, Monument, Thunderdome, Wattson’s Pylon, Fragment
• 5/24-5/28 Control: Production Yard, Thunderdome, Caustic, Barometer, Lava Siphon
• 5/31-6/3 Control: Production Yard, Thunderdome, Caustic, Barometer, Lava Siphon
• 6/11-6/17 Gun Run: Skull Town, Zeus Station, Thunderdome, Wattson, Fragment, The Core
• All players in a premade Ranked squad must be within 3 Rank tiers of each other or they will not be allowed to progress to matchmaking
• No tuning changes to be made to ranked scoring for the launch of Upheaval

Dev Note: While we are happy with how Breakout Ranked was received, there is some feedback that we want to address for the start of Upheaval. As always, we’ll be monitoring feedback and data for any required tuning changes during the season and any major updates required for the future.

Season Reset

• If you ended your last season in Rookie, you will be reset to 1 RP
• If you ended your last season above Rookie, you will be reset to Bronze IV

Split Timing

• Split 2 will take place at the same time as the .1 patch, not a week after like in previous seasons

• If you do not achieve this, you will get the normal version of your badge

WORLD SYSTEMS

• Improved end ring generation system
• Equipping an Evac Tower or Mobile Respawn Beacon will no longer close the inventories of all other players in the match
• Firing Range : fixed some edge cases where Legend change was available when it shouldn’t be
• Fixed occasional crash when interacting with an enemy’s crafted banner
• “Mischief Medic” no longer appears as “Highlighted Healer”
• Olympus : players can no longer enter/exit Vault without key
• Survey Beacons and Ring Consoles should now be pingable again from the map
• When hip firing with the Devotion, it will now properly track its reticle
• Ballistic : duration of speedy whistler restored to 2s

QUALITY OF LIFE

• Additional security improvements
• Airdropping Replicators now project a beam upwards as they are descending to help differentiate them from other airdrops
• Back by popular demand, you can requeue at the end of Pubs BR and Mixtape matches
• Ballistic : can now add any locked-set weapon into the sling where it will be converted to the proper locked-set tier and restored to its original state when being moved out (red-tier still not allowed)
• Death Box Flyers : option to automatically ping the location of the Death Box will be prompted when knocking it from a Flyer’s grasp
• Improved the choice of consumables that are auto-selected when either reaching full health, reaching full shields, or when dropping your last selected item. The new choice should more intelligently select shield consumables or prioritize syringes for quick healing. These changes were made to help new players have more optimal outcomes.
• Improved use interactions with doors when self res is available
• Map spawn audit for all Mixtape Modes: Phase Runner, Habitat, Thunderdome, Zeus Station
• Upgraded to the latest version of Easy Anti-Cheat
• Should now go through all translucent surfaces like windows
• Works similar to healing items: hold the Grenade button to open the Ordnance Wheel, hover on an ordnance item, select Ping to request

Thunderdome

• Airdrop location adjustments
• Moved C capture point to landing pad
• Adjusted spawns attached to B capture point
• Added new "Map Detail" PC video setting to adjust the amount of environmental decoration and set dressing (this may improve performance for players with low-spec PCs and those targeting high framerates)
• Changed the way players opt-in to the DX12 beta: if you're playing via the DirectX 12 beta now, the launch argument "-eac_launcher_settings SettingsDX12.json" should be changed to "-anticheat_settings=SettingsDX12.json"
• Improved accuracy and visual fidelity of baked environment lighting for static outdoor objects
• Improved accuracy of baked lighting for dynamic objects, to avoid situations where Legends would appear unlit
• Significantly improved CPU performance of the Rendering Hardware Interface (RHI), mostly benefitting the PC DirectX 12 beta

Nessie Note: Nessie would like to congratulate everyone on the success of finally finding Blue Nessie. Our girl is finally free! The Nessie Army is now complete!

Mets ace could be in line for rehab assignment as he nears anticipated return date

T he New York Mets have received encouraging news regarding the recovery of their injured ace Kodai Senga. The Japanese righty has yet to take the mound in 2024 after straining his right posterior capsule in his right shoulder earlier this spring.

Though, according to SNY’s Alex Smith, Senga felt great after throwing two simulated innings in Mets batting practice on Saturday and could be sent for a rehab assignment “in the next few days,” as manager Carlos Mendoza revealed.

Mets will get a major boost from Kodai Senga’s return later this spring

Senga’s absence has been felt throughout the early portion of the year. The Mets (16-18) are fourth in the NL East and boast a pitching rotation that ranks No. 20 in the Majors with a 1.31 WHIP.

While the Mets have been spectacular in striking out batters with 319 K’s on the campaign, good for No. 4 in the big leagues, they concede an average of 4.35 runs per game, which places them at No. 16 overall. Their failure to deliver wins at an elite level speaks to their need for Senga to return.

The 2023 All-Star earned such honors in his rookie outing after delivering 202 strikeouts behind a pristine 2.98 ERA and 1.22 WHIP. He went 12-7 that year and was the brightest spot in the Mets’ rotation.

When will Senga take the mound for the Mets in 2024?

Now, Senga and his invaluable talent can be put on display in what the team is hoping will be later in May. He is eligible to come off of the IL on May 27 and the team has said that the 31-year-old is on pace to meet that timeline.

Title : Active carbons as nanoporous materials for solving of environmental problems

However, up to now, the main carriers of catalytic additives have been mineral sorbents: silica gels, alumogels. This is obviously due to the fact that they consist of pure homogeneous components SiO2 and Al2O3, respectively. It is generally known that impurities, especially the ash elements, are catalytic poisons that reduce the effectiveness of the catalyst. Therefore, carbon sorbents with 5-15% by weight of ash elements in their composition are not used in the above mentioned technologies. However, in such an important field as a gas-mask technique, carbon sorbents (active carbons) are carriers of catalytic additives, providing effective protection of a person against any types of potent poisonous substances (PPS). In ESPE “JSC "Neorganika" there has been developed the technology of unique ashless spherical carbon carrier-catalysts by the method of liquid forming of furfural copolymers with subsequent gas-vapor activation, brand PAC. Active carbons PAC have 100% qualitative characteristics of the three main properties of carbon sorbents: strength - 100%, the proportion of sorbing pores in the pore space – 100%, purity - 100% (ash content is close to zero). A particularly outstanding feature of active PAC carbons is their uniquely high mechanical compressive strength of 740 ± 40 MPa, which is 3-7 times larger than that of  such materials as granite, quartzite, electric coal, and is comparable to the value for cast iron - 400-1000 MPa. This allows the PAC to operate under severe conditions in moving and fluidized beds.  Obviously, it is time to actively develop catalysts based on PAC sorbents for oil refining, petrochemicals, gas processing and various technologies of organic synthesis.

Victor M. Mukhin was born in 1946 in the town of Orsk, Russia. In 1970 he graduated the Technological Institute in Leningrad. Victor M. Mukhin was directed to work to the scientific-industrial organization "Neorganika" (Elektrostal, Moscow region) where he is working during 47 years, at present as the head of the laboratory of carbon sorbents.     Victor M. Mukhin defended a Ph. D. thesis and a doctoral thesis at the Mendeleev University of Chemical Technology of Russia (in 1979 and 1997 accordingly). Professor of Mendeleev University of Chemical Technology of Russia. Scientific interests: production, investigation and application of active carbons, technological and ecological carbon-adsorptive processes, environmental protection, production of ecologically clean food.

The oxygen activity is studied by oxygen sensors during the oxidation period in experimental heat of a superalloy in a 5-t electric arc furnace. The results of chemical analysis of metal and slag samples are used to calculate the activities of the metallic and oxide solution components using the energy parameters of the models of a pseudosubregular solution for the melt and a pseudoregular ionic solution for the slag, which were determined and presented in our earlier works. Equations are derived for the activity of oxygen in equilibrium with all melt components simultaneously and with each component individually. The entire oxidation process and the oxidation reaction of each metallic solution component are analyzed by comparing the actual and equilibrium oxygen activities in the metal at the beginning, middle, and end of the oxidation period of heat. The driving forces of the oxidation process are calculated from the difference between the actual and equilibrium chemical potentials of oxygen.

Apex Legends Season 21, Upheaval , is poised to live up to its namesake. As always, the new season brings a new battle pass, complete with tiers of cosmetics to unlock. But Season 21 also heralds of a new hero, the return of a popular mode, and an overhaul of an existing map.

Here’s what time Apex Legends Season 21 releases in your time zone, and what to expect from the new season.

What time does Apex Legends Season 21 release?

Based on previous release times, Apex Legends ’ Season 21 launches on Tuesday, May. 7, 2024 , at the same time all around the world. Here’s when it’ll release in your time zone:

• 10 a.m. PDT for the west coast of North America
• 1 p.m. EDT for the east coast of North America
• 6 p.m. BST for the U.K.
• 7 p.m. CEST for Paris
• 2 a.m. JST on May. 9 for Tokyo

As with all online launches, be ready for the possibility of queue times and delays to impact the above launch times.

What’s new in Apex Legends Season 21?

At a glance, here are the three biggest changes coming to Season 21 in Apex Legends :

• Solos mode returns right from the start of the season, as a replacement for the Duos mode. Solos will run through June 24, 2024. As IGN reports , the player cap for Solos is 50.
• Apex Legends will introduce a new legend with Season 21: Alter , whose repertoire consists of wormhole-like abilities. Her passive ability allows you to snag an item from faraway death boxes, while her tactical ability essentially allows you to create portals. Alter’s ultimate ability, meanwhile, is “void Nexus,” which allows you to place a beacon that your teammates can then teleport back to.
• The Broken Moon map has seen a total upheaval, replete with a visual and geographical overhaul alongside tons of new points of interest. You can see a full rundown of the changes to the map over at the EA blog .
