A Unix timestamp (also called Epoch time or POSIX time) is the number of seconds that have elapsed since January 1, 1970, 00:00:00 UTC — known as the Unix Epoch. It is a timezone-independent, language-agnostic way to represent a point in time.
Systems that store Unix timestamps as a signed 32-bit integer can only represent dates up to January 19, 2038, 03:14:07 UTC. After that point the value overflows and wraps to a large negative number — representing a date in 1901.
