Frequently Asked Questions

What is a Unix timestamp?

A Unix timestamp counts the number of seconds elapsed since January 1, 1970, 00:00:00 UTC (the "Unix Epoch"). It is timezone-independent and universally supported.

What is the Y2K38 problem?

In 2038, 32-bit Unix timestamps will overflow (max value: 2,147,483,647 sec = Jan 19, 2038). Modern systems use 64-bit timestamps to avoid this.
