Unix timestamp FAQ
What is a Unix timestamp?
A Unix timestamp is the number of seconds since 00:00:00 UTC on January 1, 1970.
Is Unix time based on my local time zone?
No. Unix time is counted from a UTC reference point. Local time zone only affects the calendar display.
Should I use seconds or milliseconds?
Use seconds when software or a service asks for epoch seconds, and milliseconds when JavaScript or logs expect epoch milliseconds.
