Managing Time like a Time Lord: It's bigger on the inside
summary
Claims that UTC storage and localized presentation solve most issues, backed by concrete examples: 37 active time zones, 15/30/45 minute offsets, DST oddities like the Navajo Nation and a short-lived North Korea shift. Demonstrations use Python tools: pytz for zones, dateutil for relativedelta, freezegun to freeze time in tests. Reproducible failures include acceptance tests that fail nightly between 8pm–midnight from unspecified timezone handling, and gotchas with datetime.replace versus normalize, calendar.monthrange, and datetime resolution.
