This one I fully read. The best collection of time zone oddities that I’ve ever seen. The first three highlights are already very fun:
“- Asia/Kathmandu has a weird offset from UTC
- Africa/Casablanca doesn’t fit into the timezone model cleanly, so it’s hard-coded
- America/Nuuk does daylight savings at -01:00 (yes, with a negative)”
