Frequently Asked Questions
What is a Unix timestamp?
A Unix timestamp (Epoch Time) is a number representing the time elapsed since January 1, 1970 00:00:00 UTC in seconds (or milliseconds). It's widely used in computer systems because it represents the same moment in time regardless of timezone.
What's the difference between 10-digit and 13-digit timestamps?
10-digit timestamps are in seconds, while 13-digit timestamps are in milliseconds. JavaScript's Date.now() returns milliseconds, while most Unix system commands use seconds.
What is the Year 2038 problem?
On 32-bit systems that store Unix timestamps as signed integers, an overflow will occur on January 19, 2038. Most modern systems use 64-bit integers to solve this issue.
How are timezones handled?
Unix timestamps are based on UTC. When displaying local time, the browser automatically applies the user's timezone. Using UTC or timestamps for API communication is always recommended.
