Questions
What is a Unix timestamp?
The number of seconds since 1 January 1970 00:00:00 UTC (the “Unix epoch”). Many systems, including JavaScript, use milliseconds instead.
How do you know if it is seconds or milliseconds?
Values with 13 or more digits are treated as milliseconds, shorter values as seconds. You can override this.
