What a Unix timestamp is
A Unix timestamp is a number that counts time from 1970-01-01 00:00:00 UTC. Many APIs, logs, databases, and developer tools use it.
Seconds or milliseconds
Shorter 10-digit values are usually seconds. Longer 13-digit values are usually milliseconds. The converter explains what the number means.
UTC, local, and selected timezone
UTC is the neutral reference time. Your browser time shows your device's timezone, and the selected timezone helps compare a specific city or region.
