FAQ
A Unix timestamp (also called epoch time) is the number of seconds elapsed since January 1, 1970, 00:00:00 UTC. It is a universal way to represent a specific moment in time, independent of time zones.
A standard Unix timestamp counts seconds since the epoch. Some systems (like JavaScript's Date.now()) use milliseconds, which is the seconds value multiplied by 1000.
The local time shown is based on your browser's time zone setting. The Unix timestamp itself is always in UTC; local time is a display conversion.
