A Unix timestamp converter converts seconds or milliseconds elapsed since January 1, 1970 (UTC epoch) into human-readable date and time strings across UTC and local timezones.
A Unix timestamp (also known as Epoch time or POSIX time) is a system for describing a point in time defined as the number of seconds that have elapsed since 00:00:00 UTC on January 1, 1970 (the Unix Epoch), minus leap seconds. It is widely used in operating systems, databases, software applications, and API protocols for storing timestamps neutrally without timezone ambiguity.
