What is a Unix Timestamp?

A Unix timestamp (also called Epoch time) is the number of seconds that have elapsed since January 1, 1970, 00:00:00 UTC. It is a widely used standard for representing points in time in computer systems, databases, APIs, and log files.

Most programming languages and databases store time as Unix timestamps internally. JavaScript uses milliseconds (Date.now()), while Unix systems and most backend languages use seconds.
