What Is a Unix Timestamp?

A Unix timestamp (also known as Epoch time or POSIX time) is the number of seconds that have elapsed since January 1, 1970, at 00:00:00 UTC. It is widely used in programming, databases, APIs, and log files as a compact, timezone-independent way to represent a point in time.
