Understanding Unix Epoch timestamps

Unix time measures seconds elapsed since January 1, 1970 (00:00:00 UTC). It provides a timezone-neutral standard for database timestamps and log event tracking.

Seconds vs. milliseconds auto-detection

Automatically parses 10-digit timestamps (seconds) and 13-digit timestamps (milliseconds) into ISO 8601, UTC, and local browser time formats.

Private debugging for server logs

Because execution happens locally in client-side JavaScript, sensitive production timestamps or session logs remain confidential.

FREQUENTLY ASKED QUESTIONS

Does my timestamp get sent to a server?

No. Conversion is performed using client-side JavaScript in your browser, so you can disconnect from the internet and it will keep working.

How can I tell seconds from milliseconds?

10-digit numbers represent seconds (e.g. `1700000000`), while 13-digit numbers represent milliseconds (e.g. `1700000000000`).

Which timezones are displayed?

Output is displayed in universal UTC as well as your local system timezone.

Is Year 2038 safe?

Yes. JavaScript represents timestamps using 64-bit floating-point numbers, safely handling dates past 2038.
