Frequently Asked Questions

What is a Unix timestamp?

A Unix timestamp is the number of seconds elapsed since January 1, 1970 (UTC). It's used universally in programming to represent points in time in a timezone-independent way.

Does the timestamp use seconds or milliseconds?

Unix timestamps are traditionally in seconds. JavaScript uses milliseconds (multiply by 1000). This tool handles both automatically.
