FAQ

What is a Unix timestamp?

A Unix timestamp is the number of seconds elapsed since January 1, 1970 00:00:00 UTC (the 'Unix epoch'). It's timezone-independent, making it ideal for storing dates in databases.

What is the difference between seconds and milliseconds timestamps?

Unix timestamps are usually in seconds (10 digits). JavaScript's Date.now() returns milliseconds (13 digits). Divide by 1000 to convert ms to seconds.

January 19, 2038 at 03:14:07 UTC = 2,147,483,647. This is the 'Year 2038 problem' — the maximum value for a signed 32-bit integer.
