How to use Timestamp Converter
- Paste a timestamp, or press Convert this for the current time.
- Check the unit if it was not detected correctly.
- Pick a time zone to compare.
- To go the other way, enter a date and time and its time zone.
Is it private?
Yes. Timestamp Converter runs entirely in your web browser. What you type is never sent to Nolo or anyone else, and the page cannot send it anywhere: its security policy only allows it to talk to nolotools.com, which has no place to receive data. Nothing is stored either: close the page and it is gone. How Nolo works.
Questions and answers
What is a Unix timestamp?
The number of seconds since 1 January 1970 00:00:00 UTC (the Unix epoch), not counting leap seconds. JavaScript and many APIs use milliseconds instead, which is 1,000 times larger.
How does it know if my timestamp is in seconds or milliseconds?
By its length: up to 11 digits is read as seconds, 12 to 14 as milliseconds, 15 to 17 as microseconds and 18 or more as nanoseconds. You can override the unit.
Are time zones and daylight saving time handled?
Yes. It uses your browser's built-in time zone database (the IANA database, via Intl), so offsets and DST changes are correct for any date and zone.
Can I paste a date instead?
Yes. ISO 8601 dates such as 2026-01-01T12:00:00Z are understood in the first box too.
Is my data sent to a server?
No. Everything runs in your browser and your data never leaves your device. The page is not allowed to talk to any other site, so it is safe to use with real data and secrets.
