Frequently Asked Questions

What is a Unix epoch timestamp?

Unix epoch time is the number of seconds that have elapsed since January 1, 1970 UTC (midnight), excluding leap seconds.

How does the tool distinguish seconds from milliseconds?

10-digit timestamps (e.g. 1773000000) are treated as seconds, while 13-digit numbers are parsed as milliseconds.

Can I convert an ISO date string back into an epoch number?

Yes. Paste any valid ISO 8601 string (e.g. 2026-09-09T00:00:00Z) to get both second and millisecond timestamps.

Is my timezone data shared?

No. Conversion uses standard JavaScript `Date` and `Intl` APIs locally in your browser memory.

Can I enter 'now' to get the current epoch time?

Yes. Typing 'now' or leaving the input blank produces the current exact timestamp.
