Frequently asked questions

What is a Unix timestamp?

It's the number of seconds (or milliseconds) since January 1, 1970 UTC — a compact, timezone-free way to store a moment in time.

Seconds or milliseconds?

Unix timestamps are usually in seconds, but JavaScript uses milliseconds. The tool handles both so you don't have to guess.

Does it show my local time?

Yes — converted dates are shown in your local timezone, computed in your browser.
