About Unix Timestamps
A Unix timestamp is the number of seconds since January 1, 1970 00:00:00 UTC (the "Unix Epoch"). It's the most universal way to represent a moment in time in computing — no timezones, no formatting ambiguity, just a number.

Seconds vs. Milliseconds
Unix timestamps traditionally count seconds (10 digits). JavaScript's Date.now() returns milliseconds (13 digits). Our converter auto-detects which you're using.
