It's about time
summary
Dates carry centuries of exceptions: Gregorian tweaks, the October Revolution shift, Sweden's one-off February 30 in 1712, Berlin's historical LMT of +53 minutes, and odd Australian offsets like Eucla +8:45 or Lord Howe's 30‑minute DST. Code-level advice is concrete: prefer datetime with use pytz for Olson updates, localize naive datetimes before math and normalize after arithmetic, watch the 32‑bit epoch overflow at 03:14:07 19 Jan 2038, log ISO 8601, and always include year and timezone on display.
