How it works

One instant, several representations

A Unix timestamp counts from 1970-01-01 00:00:00 UTC. A time zone changes only how that instant is displayed.

Large integers stay intact, and every conversion runs locally in this page.

FAQ

Timestamp questions

Is a Unix timestamp in seconds or milliseconds?

It can be either. UnixTick automatically detects seconds, milliseconds, microseconds or nanoseconds and shows its confidence.

Does a Unix timestamp include a time zone?

No. It represents one instant in UTC. A time zone changes the readable date.

Can I convert microsecond or nanosecond timestamps?

Yes. UnixTick preserves the full integer and displays the corresponding six- or nine-digit fractional precision.

Are my values uploaded?

No. Conversions run locally in your browser.
