FAQs
What is a Unix timestamp?
The number of seconds since 1 January 1970 00:00:00 UTC, used by computers and APIs to represent dates as a single number.
Seconds or milliseconds?
The tool detects this automatically: values with 13 or more digits are treated as milliseconds, shorter ones as seconds.
Which time zone is shown?
You get the UTC time, the equivalent in your device’s local time zone, and the ISO 8601 form, so every base is covered.
