Time zone notes
- • UNIX timestamps are always UTC; local inputs are converted for you.
- • Use datetime-local for quick comparisons with schedule builders or cron.
- • Copy the readable output to share context when coordinating across teams.
- • Keep consistent offsets by double-checking daylight saving shifts.
