If you've never written time code, you have no idea how fucked up time code is to write.
You know the common expression "it's not rocket science"?
Time code is fucking rocket science. Grownup programmers *never* write that shit by hand, they *always* turn to people who write it for a living.
Classic joke, here.

@GeePawHill I remember some issue around the Japanese imperial calendar. It's based upon the reign so we're in Riewa 8. The issue for the first time there are computers with time around for the change (8 years ago) and the old monarch dying. You can't pre-calculate it because nobody knows when the reign changes.
