Frequently asked questions

What is a Unix timestamp?

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

Does it support milliseconds?

Yes. Paste a value in seconds or milliseconds — the converter detects the length and handles both.

What outputs do I get?

Your local time, UTC, ISO 8601 format and a friendly relative time (like 'in 2 days'). Converting a date back gives you seconds and milliseconds.

Is anything uploaded?

No. All conversions run in your browser.
