What is the difference between seconds and milliseconds in timestamps?

Standard Unix timestamps are in seconds (10 digits). JavaScript and many modern systems use milliseconds (13 digits). Our tool can automatically detect and handle both formats.

Is the output in UTC or my local time?

The tool displays the converted date in both UTC (Coordinated Universal Time) and your computer's local timezone for easy comparison.
