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.
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.
Why
2100 not a leap year (divisible by 100). 2400 is a leap year (divisible by 400). Developing for dates is a minefield.
Because they're not leap years but are 0 === year % 4
Luckily, none of us will be there.
Yeah but I'll be dead so not my problem lmao
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.
In every project I've ever worked on, there's been somebody who must have been like, "HurDur Storing timestamps in UTC is for losers. Nyeaahh!"
And if I ever find that person, I'm going to get one of those foam pool noodles, and whack him/her over the head with it until I've successfully vented all my frustrations.
I just use a float between 0 and 1 with 0 being 1970 and 1 being the predicted heat death of the universe.
The only time using UTC breaks down is when any sort of time change gets involved.
If I say I want a reminder at 9am six months from now and you store that as UTC, a day light savings change will mean I get my reminder an hour early or late depending on where in the world I am
But wouldn't you calculate the time in the future in the right time zone and then store it back as UTC?
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

I hope the homeassistant guys already have this covered, because I didn't use it 4 years ago to know
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'm not worried at all - I love me some tz database.
