Frequently Asked Questions
What is a Unix timestamp?
A Unix timestamp (also called Epoch time) is the number of seconds that have elapsed since January 1, 1970, 00:00:00 UTC. It's a universal way to represent a specific moment in time.
What's the difference between seconds and milliseconds?
Unix timestamps are traditionally in seconds, but JavaScript and many modern APIs use milliseconds (1000x larger). A 10-digit number is seconds, 13-digit is milliseconds.
What is the Year 2038 problem?
32-bit systems store timestamps as signed integers, which will overflow on January 19, 2038. Modern 64-bit systems don't have this limitation.
How do I get the current Unix timestamp?
In JavaScript: Date.now() (milliseconds) or Math.floor(Date.now()/1000) (seconds). In Python: import time; time.time(). In PHP: time().
What timezone do Unix timestamps use?
Unix timestamps are always in UTC (Coordinated Universal Time). They represent an absolute moment in time, independent of timezone.
