How to use Unix timestamp converter

Enter a Unix timestamp in seconds or milliseconds, or a readable date.
Convert it in the direction you need.
Check the converted date or timestamp before using it in code.

A good use for this

Reading a timestamp from a log, a database, or an API as a human date, or turning a date into a timestamp for code.

Limits

Seconds and milliseconds look alike but differ by a factor of a thousand — a timestamp converted in the wrong unit lands in 1970 or in the year 50,000, so check the unit first.
