Frequently Asked Questions

What is a Unix Epoch timestamp?

It represents the total elapsed seconds since January 1, 1970 00:00:00 UTC, providing a universal, timezone-agnostic timestamp for computers.

10-digit timestamps measure in seconds (standard in Linux, Python, PHP), while 13-digit timestamps measure in milliseconds (used in JavaScript Date.now()).
