Frequently Asked Questions

What is Unix epoch time?

Unix epoch time (or POSIX time) is the number of seconds that have elapsed since 00:00:00 UTC, Thursday, 1 January 1970, not counting leap seconds.

How do I convert milliseconds instead of seconds?

The converter automatically detects if the input number is in seconds (10 digits) or milliseconds (13 digits) and adjusts.

Is local timezone supported?

Yes, it reads your browser's local system timezone to display conversions, along with standard UTC.
