Frequently Asked Questions
What is a Unix timestamp?
A Unix timestamp (also called Epoch time) is the number of seconds that have elapsed since January 1, 1970 00:00:00 UTC. It is widely used in programming to represent points in time as a single number.
Should I use seconds or milliseconds?
Most Unix timestamps are in seconds (10 digits, e.g. 1700000000). JavaScript and some APIs use milliseconds (13 digits). The tool supports both — just select the correct unit before converting.
Does the live clock update automatically?
Yes. Click the Start Live button to see the current Unix timestamp update every second in both seconds and milliseconds. Click Stop to pause.
