I know this isn't any kind of surprise, and yet, well...
2100 and 2400 will be a shitshow

Not as much as 2038
Yeah that's a different shitshow but agreed it is likely to be worse - like y2k the effects are smeared out before and after the date.
Why?
32bit systems will stop working. The Unix timestamp, which increases by 1 every second and started the first second of 1970, will reach the max of 32 bit integers. Bad things will follow.
This has already been patched on all 64 bit OSes though - whatever 32 bit systems are still in existence in another 15 years will just roll their dates back 50 years and add another layer of duct tape to their jerry-rigged existence
2038 will certainly be a shit show
Yeah but I'll be dead so not my problem lmao
Nah.
Same thing happened in 2000 and it was a mouse’s fart.
Because of months of preparation. I know, I was doing it.
And now that every time library has been updated, we're safe until our grandchildren reimplement those bugs in a language that has not yet been invented.
I've already seen reimplementation of 2 digit dates here and there.
LOL fuck those guys.
Fortunately I will not be involved. Hopefully I can make something from 2038 though.
You’re not the only one forseeing a nice consultant payday there.
I went to uni in the mid 90s when Y2K prep was all the rage, went back to do another degree 20 years later. It was interesting to see the graffiti in the CS toilets. Two digits up to about 1996, four digits for a decade, then back to two.
Why
2100 not a leap year (divisible by 100). 2400 is a leap year (divisible by 400). Developing for dates is a minefield.
Now imagine working on non Georgian, and the year is 2060
Luckily, none of us will be there.
Won’t the computer’s clock reset every time you go to sleep and stop cranking the power generator?
Yeah who knows if our computers are sticks by either date
Then there's my code, which didn't even survive the time change.
Your code made it to the time change!!?
Same... The change from 12 to 1
People who haven't had a birthday in almost four years are like

Programming aside, where I live in Southern Europe we have a tradition according to which leap years bring bad luck. After 2020, I don't know what to expect... nuclear apocalypse maybe?
Wait, 2020 wasn't a bad luck year?
Previous commenter meant "what could be worse than the bad luck leap year 2020?"
Always, always, always, without taking any shortcuts, use a tzinfo library for your language.
Anyone who doesn't use standardized libraries for tz should be summarily tried.
I'm not worried about my code, I'm (very slightly) worried about all the date libraries I used because I didn't want code that shit again for the billionth time.
Your comment made me go look at the source for moment.js. It has "leap" 13 times and the code looks correct. I assume they test stuff like this.
Yeah, I'm generally using the common data/time libraries in most (if not all) languages and I'm pretty sure they've all been through more than 1 leap year at this point. I just never 100% trust the code I don't control - 99.9% maybe, but never 100.
I just never 100% trust the code I don't control
I never 100% trust the code I do control. Partially because a lot of it is inherited but also because I know corners were cut but I can't always remember when and where
I worked in broadcasting (programming broadcasting applications), everything is done with PTP (Precise Time Protocol) and TC (timecode) in video. We had to support leap second, it's not as easy, but in the end, insert black frames for 1s and that's it.
I hope leap days are handled a bit more sophisticated!
Insert black frames for 24 hours and you're good to go!
Haha yes, no problem with those 😁
Yeah... I patched some unit tests...
Before it was 50/50 that they'd fail on leap day, but after the patch it's 50/50.
I hope the homeassistant guys already have this covered, because I didn't use it 4 years ago to know
We found an use case with Page duty and it's ical feed already...
