Post funny things about programming here! (Or just rant about your favourite programming language.)
Timezones are fine to program around.
DST is a bit of a pickle to plan around, but can be done just fine by a computer program.
Historical dates; considering leap years, skipped leap years, and times when leap years weren't a thing or when humanity just decided we skip a bunch of years; are the bane of all that is good.

I hear timezone names can also be a slight issue at times, some Australians call the eastern time zone EST. Leap years aren't so bad at times either though. Kind of agree with the rest of it, much of the complexity is from historical dates.
We call eastern coast time AEST
I know most call it AEST, but there are some who call it EST.
