FAQ

What is a Unix timestamp?

A Unix timestamp is the number of seconds (or milliseconds) elapsed since January 1, 1970 00:00:00 UTC. Databases and APIs commonly use this format to store time values.

What is the difference between 10-digit and 13-digit timestamps?

A 10-digit number represents Unix seconds (precision to the second). A 13-digit number represents Unix milliseconds (precision to the millisecond). This tool auto-detects the format.

Which timezones are supported?

The tool displays both UTC (ISO 8601) and your browser's local timezone, so you can easily compare across zones.
