About Unix Timestamps

A Unix timestamp (also called epoch time or POSIX time) is the number of seconds that have elapsed since January 1, 1970 at 00:00:00 UTC — known as the Unix epoch. It's the universal way to represent time in programming.

When Are Timestamps Used?

Database storage (created_at, updated_at fields)
API responses and request headers
Log file entries and event tracking
JWT token expiration (exp claim)
Cache control and HTTP headers

Seconds vs Milliseconds

Most Unix timestamps are in seconds (10 digits). JavaScript's Date.now() returns milliseconds (13 digits). This tool automatically detects the format.
