Formula
Unix time = seconds since 1970-01-01T00:00:00Z. ISO time = the same instant in calendar form. Multiply seconds by 1,000 for milliseconds.
Example
0 → 1970-01-01T00:00:00Z. 1700000000 → 14 Nov 2023, 22:13:20 UTC.
Common examples
1700000000
= 2023-11-14 22:13 UTC.

Frequently asked
Seconds or milliseconds?
We use seconds (the Unix standard). Multiply by 1,000 for JavaScript Date().
What about negative timestamps?
Allowed — they represent dates before 1970-01-01 UTC.
Time zone?
UTC is shown alongside your device's local time, so you can sanity-check both.
