What is a Unix Timestamp?

A Unix timestamp (also called epoch time) is the number of seconds that have elapsed since January 1, 1970 at 00:00:00 UTC. It is the most widely used system for tracking time in software — used in databases, APIs, logs, and virtually every programming language.

Seconds vs Milliseconds

Unix timestamps are typically in seconds (10 digits, e.g. 1716000000) but JavaScript and many APIs use milliseconds (13 digits, e.g. 1716000000000). This tool auto-detects which one you have pasted.
