Frequently Asked Questions

What is a Unix timestamp?

A Unix timestamp (epoch time) is the number of seconds elapsed since January 1, 1970, 00:00:00 UTC. It is a universal way to represent dates and times in programming, independent of time zones.

What is the difference between seconds and milliseconds timestamps?

Unix timestamps in seconds are 10 digits (e.g., 1700000000). Millisecond timestamps are 13 digits (e.g., 1700000000000). JavaScript's Date.now() returns milliseconds; most APIs use seconds.

What is the Unix timestamp for the year 2038 problem?

The Unix timestamp 2147483647 represents 19 January 2038, 03:14:07 UTC — the maximum value for a 32-bit signed integer. Systems using 32-bit timestamps will overflow on this date, similar to Y2K.
