What is a Unix timestamp?

A Unix timestamp counts elapsed time from January 1, 1970 at 00:00:00 UTC. Many APIs and databases store dates this way because a single number is easy to compare, sort, and move between systems.

Seconds or milliseconds?

Traditional Unix timestamps use seconds. JavaScript and some APIs use milliseconds, producing a number roughly one thousand times larger. Auto detect handles most modern timestamps, or you can choose the unit explicitly.
