Conversion Formula
→
ISO 8601 timestamps combine date, time, and optional time zone offset information. The converter parses the ISO value into an instant and formats it as UTC, local time, Unix time, or another readable format.
Examples
- 2026-06-29T12:30:00Z = UTC timestamp
- 2026-06-29T14:30:00+02:00 = the same instant as 12:30 UTC
- Convert an API timestamp into local readable time
