About Unix Timestamps

A Unix timestamp counts the number of seconds since January 1, 1970 00:00:00 UTC (the Unix Epoch). It's widely used in programming for storing and comparing dates because it's timezone-independent and easy to calculate with. JavaScript uses milliseconds, while most other languages use seconds.
