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, 00:00:00 UTC. This date is known as the Unix epoch.

Unix timestamps are widely used in programming and databases because they provide a simple, universal way to represent time that is independent of time zones and easy to compare and calculate.
