Frequently asked questions
What is a Unix timestamp?+
A Unix timestamp is the number of seconds that have elapsed since January 1, 1970 at 00:00:00 UTC. It is a universal way to represent a point in time as a single number.
Is the timestamp generated on a server?+
No. Timestamp generation runs in your browser using your device's clock. No data is sent to any server.
What is the difference between seconds and milliseconds?+
Unix timestamps in seconds are 10 digits, used by most backend systems and databases. Millisecond timestamps are 13 digits, commonly used in JavaScript and frontend applications.
Does it account for time zones?+
Yes. The tool shows timestamps in both UTC and your local time zone. Unix timestamps themselves are always UTC-based, so the underlying value is the same regardless of your location.
