What a Unix timestamp is
It is the number of seconds since 00:00:00 UTC on 1 January 1970, the "Unix epoch". Because it is a plain integer in UTC, it is unambiguous across time zones, which is why logs, APIs and databases use it. Ten digits is seconds; thirteen is milliseconds. It is always UTC — the local time shown here is your browser applying its own zone.
