Frequently Asked Questions
What is a Unix timestamp?
A Unix timestamp (also called Epoch time or POSIX time) is the number of seconds that have elapsed since January 1, 1970 00:00:00 UTC. It is widely used in programming, databases, and APIs as a simple, timezone-independent way to represent time.
What is the Unix Epoch?
The Unix Epoch is the reference point: January 1, 1970, at 00:00:00 UTC. All Unix timestamps are measured as seconds before or after this moment. Negative timestamps represent dates before 1970.
Why do some timestamps use milliseconds?
JavaScript's Date.now() returns milliseconds since the Epoch, while most Unix systems use seconds. This tool shows both. To convert milliseconds to seconds, divide by 1000. Many APIs accept either format.
Will Unix timestamps run out?
32-bit systems store timestamps as a signed 32-bit integer, which will overflow on January 19, 2038 (the Y2K38 problem). Most modern systems use 64-bit integers, which will last billions of years.
