A Unix timestamp is the number of seconds (or milliseconds) since January 1, 1970 00:00:00 UTC. It's widely used in programming, databases, and APIs.
Seconds or milliseconds?
The tool auto-detects: values over 1 trillion are treated as milliseconds, otherwise as seconds. Most APIs use seconds; JavaScript's Date.now() uses milliseconds.
