@0xabad1dea I like how they don't directly acknowledge it's a leap year issue

@outadoc @0xabad1dea in a way I think they did the sensible thing: provide the workaround. The majority of users don't care about the reason, they just want to run their game.

@0xabad1dea the real end of technology wasn't y2k, it won't be 2038, but it might be leap years

@hellpie @0xabad1dea We had some industrial equipment that sort of shit itself when transitioning from 2019 to 2020.

It went from December 31st 2019 to January 1st 34210 or something batshit like that.

@DeltaWye @hellpie @0xabad1dea I've programmed code in 1993 that assumed that '31.12.19' means '31.12.2019' and '01.01.20' means '01.01.1920'. I'm still using that program and had to change the sourcecode in 2020.

Yes, this is how some developers "fixed" the Y2K bugs that were given them to fix.

Kick it down the road 20 years, and if anybody's still using the equipment it'll be somebody else's problem to fix.

@hellpie @0xabad1dea Japanese date format is almost certainly something that they have a solution for-you *could* just indicate the difference in the U.I., but store the date format the same way internally.
That,and you can test it on any given day much easier.Leap years you have to check for specific years it's being set for (Generally) every four years, that sounds like the easy check...except for the exceptions when within 4 years it's not a leap year.
It's a harder version of DST checking...

29 February at 20:02 | Open on mstdn.ca
Alexander The 1st

@hellpie @0xabad1dea ...which is to say that Spring Forward and Fall Back DST checks (And the related differences with regards to which countries and time zones switch on DST and when, and which direction.) is my bet on what is likely to be the next thing that trips until they can fix it after a hotfix of just manually changing the time.

The fun part with that manager is that they apparently didn't understand what they were saying.

So you have 10 ifs... that means 1024 paths through that piece of code... all which have to be considered and tested.

With 20 ifs it's 1048576 paths.

@Mossop @0xabad1dea If I may add to the falsehoods:

1. DST doesn't exist
2. DST always exists
3. The dates that DST changes happen are the same everywhere
4. The dates that DST changes don't change
5. A person lives and works in the same time zone
6. A person's house is in a single time zone
7. A stationary object doesn't change timezones

I'm going to throw this one in just for good measure (though, to be fair, the story that goes with it wasn't about a programmer):
2.5: UTC experiences DST if the locale experiences DST.

This is a programming error. The library behaves exactly as documented:

"For the datetime.strptime() class method, the default value is 1900-01-01T00:00:00.000: any components not specified in the format string will be pulled from the default value."

If you want your software to handle leap years correctly, you have to give it a chance to know which year we are talking about 😉

Edit/More stuff: I just wanted to add that the first thing we were taught when we learned java in uni was date validation especially for leap years, iirc it was year%5 == 0 I think
But I like to think that the code was all if statements or perhaps a huge switch with tens of cases, and that's why you always use libraries and never do things yourself, but I'll fricking do it anyways kekw :btr_bocchi_panic:
