Frequently asked questions

What is a Unix timestamp?

A Unix timestamp is the number of seconds that have elapsed since January 1, 1970 00:00:00 UTC (the Unix Epoch). It is used universally in programming to represent dates and times.

What is the difference between seconds and milliseconds timestamps?

Unix timestamps are typically in seconds (10 digits). JavaScript uses milliseconds (13 digits). For example 1698765432 is seconds and 1698765432000 is milliseconds.

Why do developers use Unix timestamps?

Unix timestamps are timezone independent, easy to compare, sort and calculate differences, and take less storage than formatted date strings. They are used in databases, APIs, JWT tokens and log files.

What is the maximum Unix timestamp?

The maximum 32-bit Unix timestamp is 2147483647 which corresponds to January 19, 2038. This is known as the Year 2038 problem. 64-bit systems can store timestamps far beyond this.

What is ISO 8601?

ISO 8601 is the international standard for date and time representation. Example: 2026-04-18T12:00:00Z. The Z means UTC timezone.
