What is Unix Epoch Time?
Unix Epoch
January 1, 1970 00:00:00 UTC

The starting point for Unix time (timestamp = 0)

Seconds Precision

Standard Unix timestamps use seconds. Most systems and APIs use this format.

Milliseconds Precision

JavaScript and some APIs use milliseconds (13 digits instead of 10).

Year 2038 Problem

32-bit systems will overflow on January 19, 2038. Use 64-bit for future dates.
