How it works
A Unix timestamp counts the seconds since 00:00:00 UTC on 1 January 1970, called the epoch. Values with 12 or more digits are treated as milliseconds, the format JavaScript uses. The tool shows the same moment in UTC and in your local time zone.
Example
The timestamp 1700000000 is 22:13:20 UTC on 14 November 2023.
