Online Unix timestamp converter

This timestamp tool recognizes Unix timestamps in seconds or milliseconds and displays the corresponding date and time. Unix timestamps are based on UTC; the tool shows local time and UTC side by side to help diagnose time zone differences.

How can I tell seconds from milliseconds?

A typical seconds timestamp has about 10 digits, while milliseconds have about 13. Check the unit before converting: multiplying or dividing by 1,000 incorrectly can move the result far from the intended date.
