An ISO date-time without a time zone (for example 2024-01-15T09:30) is read in UTC. Add Z or an offset for an exact UTC value.

Convert Unix timestamps and dates both ways

Paste a Unix timestamp to read it in UTC and your local time zone, or type an ISO date-time to get the matching epoch seconds and milliseconds. Handy for debugging logs, API payloads, JWT exp and iat claims, and database rows without leaving the page.
