Frequently asked questions

What is a Unix timestamp?

It's the number of seconds (or milliseconds) elapsed since 00:00:00 UTC on 1 January 1970, known as the Unix epoch.

How does it know seconds vs milliseconds?

By length: 10-digit values are treated as seconds and 13-digit values as milliseconds, which covers current dates correctly.
