I'm asking to know what to write in my documentation.
MDN describes it as:
A Number representing the milliseconds elapsed since the UNIX epoch.
While W3Schools describes it as:
the number of milliseconds since 1970/01/01
However, those are just descriptions. The Wikipedia page of Unix time states:
Unix time is a system for describing instants in time, defined as the number of seconds that have elapsed since 00:00:00 Coordinated Universal Time (UTC), Thursday, 1 January 1970 [...]
Seconds. Not milliseconds, as returned by Date.now(). So I can't really call it the "unix time format" as well.
Does the "number representing the milliseconds elapsed since the UNIX epoch" time format have a more concise name?
