What is a Unix timestamp?

A Unix timestamp is the number of seconds, or sometimes milliseconds, that have passed since January 1, 1970 at UTC. It is the standard way computers store and communicate points in time.

Does the tool handle milliseconds?

Yes, it accepts both seconds and milliseconds and detects the unit from the length of the number. This avoids using a milliseconds value as seconds, which would give the wrong date.

Why does the converted date look off?

Timestamps are stored in UTC, so the date and time you see depend on the time zone used for display. Check against the time zone of the system that produced the timestamp.

Yes, conversion happens entirely in your browser and your input is never uploaded. You can safely convert timestamps from logs or API responses.
