Frequently Asked Questions
- What is a Unix timestamp?
- The number of seconds that have elapsed since midnight UTC on January 1, 1970 (the "Unix epoch") — a common way for computers to represent a point in time.
- Why do some systems use milliseconds instead of seconds?
- Some languages and APIs (like JavaScript's Date.now()) use milliseconds for finer precision — divide by 1000 to get the standard Unix timestamp in seconds.
