What is a Unix timestamp?

A numeric representation of time: seconds (or milliseconds) elapsed since 1970-01-01 00:00:00 UTC.

Seconds or milliseconds?

APIs use both formats. Toggle the ms switch to change the unit.

Use the 'From date/time' field or paste a date: the tool updates the timestamp automatically.

The timestamp is UTC-based; formatting into a local date depends on the selected timezone.
