How to use the Unix Timestamp Converter

Convert Unix epoch seconds to an ISO timestamp or turn a browser-local date and time into Unix seconds.

  1. For timestamp-to-date, enter Unix seconds since 1970-01-01T00:00:00Z.
  2. For date-to-timestamp, choose a local date and time.
  3. Fieldlet uses the browser Date API for the conversion.

Common questions

Are Unix timestamps timezone-specific?

The timestamp itself represents an instant relative to UTC. A local date-time input is interpreted using the browser's local timezone before conversion.
