FAQ

What is a Unix timestamp?

A Unix timestamp (epoch time) is the number of seconds elapsed since January 1, 1970 00:00:00 UTC. It is widely used in programming and databases to represent date and time.

Does it support millisecond timestamps?

Yes. Numbers with 13 or more digits are automatically detected as millisecond timestamps. This covers the format returned by JavaScript's Date.now().

Is my data sent to a server?

No. All conversion happens locally in your browser via JavaScript. No data is ever transmitted externally.
