FAQ
What is a Unix timestamp?
A Unix timestamp (also called epoch time) counts the number of seconds elapsed since 00:00:00 UTC on 1 January 1970. It is widely used in programming, databases, and APIs because it is timezone-independent and easy to compare arithmetically.
Seconds vs milliseconds?
The tool auto-detects: 10-digit numbers are treated as seconds, 13-digit numbers as milliseconds. For ambiguous cases, use a date string instead.
