Current Unix Timestamp
A live clock that shows the current epoch time in seconds and milliseconds, ready to copy, alongside the ISO 8601 UTC date and your local time.

What is Current Unix Timestamp?
The current Unix timestamp is the number of seconds elapsed since 1 January 1970 UTC, right now. Developers need it constantly to test expiry logic, write fixtures, sign requests or check how far a server clock has drifted.
This page reads your device clock once per second and displays seconds, milliseconds, the ISO 8601 UTC date and the local time in the zone you pick. Nothing is fetched from a server, so the value is only as accurate as your computer clock.
How does it work?
- Open the page: the clock starts and refreshes by itself every second.
- Choose the display time zone, or type an IANA name, to change the local time row.
- Copy the seconds or milliseconds value at the moment you need it.
- Compare with a server value to see whether the two clocks agree.
Common use cases
- Grabbing a fresh epoch value to paste into a curl command, a Postman variable or a unit test.
- Setting a token expiry a few minutes ahead of "now" while debugging authentication.
- Checking whether a machine clock is off by comparing it with a trusted device.
- Explaining to a colleague what an epoch value looks like today.

Privacy
Current Unix Timestamp runs entirely in your browser. The text or files you provide are processed on your device and are not uploaded, logged or stored on our servers.
Limitations
The time comes from your device clock, which may be wrong or manually changed; the tool does not query a network time server.
Frequently asked questions
Is this value the same everywhere in the world?
Yes. A Unix timestamp is time-zone independent: it counts elapsed seconds since the UTC epoch. Only the local time row changes with the zone.
Why does the millisecond value change more than once a second?
The display refreshes every second, but each refresh captures the exact current millisecond, so the last digits differ every time.
Can I trust it for security-sensitive timing?
Use it for development and debugging. Security decisions must rely on a trusted server clock, because a browser clock can be changed by the user.
