Unix time is the source of all other timekeeping systems on this website. It is as accurate as JavaScript's Date library and your device's system time allow.


Calculation

This clock shouldn't need to be calculated, since dateTime already provides the Unix time.

currentDateTime.getTime();

This will also automatically skip leap seconds.
