What is a Unix timestamp?
A Unix timestamp (also called epoch time or POSIX time) is the number of seconds that have elapsed since 1 January 1970, 00:00:00 UTC, not counting leap seconds. It is a single number that represents an exact moment in time, independent of time zones — which makes it the standard way computers store and exchange time.
Because it is measured from a fixed point in UTC, the same timestamp means the same instant everywhere in the world; only its human-readable form changes with the local time zone.
Frequently Asked Questions
- What is the current Unix timestamp?
- The number above shows the current epoch time — seconds since 1 January 1970 UTC — updated every second.
- Is a Unix timestamp in seconds or milliseconds?
- The classic Unix timestamp is in seconds. JavaScript and some systems use milliseconds (1000× larger); divide by 1000 to get seconds.
- What time zone is a Unix timestamp in?
- None — it is an absolute count from a fixed UTC moment, the same everywhere. Time zones only affect how it is displayed.
- What is the Unix epoch?
- The epoch is the starting point: midnight UTC on 1 January 1970, which is timestamp 0.
