Unix time (also epoch time or POSIX time) is the number of seconds elapsed since January 1, 1970, 00:00:00 UTC, not counting leap seconds. The epoch itself is Unix time 0, but "epoch" is commonly used as a synonym for Unix time in general.
Timestamps come in different resolutions: seconds (10 digits today), milliseconds (13), microseconds (16) and nanoseconds (19). This page auto-detects the unit by digit count.
Systems that store Unix time as a signed 32-bit integer overflow on January 19, 2038 — the Year 2038 problem. Modern 64-bit time values do not have this limitation.
