This free online digital clock shows the current time ticking live in real time — with seconds, milliseconds and microseconds — for any time zone you choose. It uses your device clock and runs entirely in your browser, so nothing is uploaded.

Milliseconds and microseconds are read from the browser high-resolution timer. Browsers clamp this timer for security, so the smallest digits are best-effort, not a true hardware microsecond clock.
How to use Digital Clock
1Read the live time — hours, minutes, seconds, then the animated milliseconds and microseconds.
2Pick a time zone from the list, or tap “My zone” to use your own.
3Switch between 24-hour and 12-hour format.
4Copy the current Unix timestamp (ms) or ISO string with one tap.
Frequently asked questions
Is the time accurate?
It reads your device clock, so it is as accurate as your computer or phone is (which is usually synced to internet time automatically).
Can it really show microseconds?
It reads the browser high-resolution timer for the sub-millisecond digits. Browsers clamp that timer for security, so the smallest digits are best-effort rather than a true hardware microsecond clock.
Is anything uploaded?
No. The clock runs entirely in your browser using your device time and time-zone data; nothing is sent anywhere.
Can I see the time in another country?
Yes. Choose any IANA time zone from the picker and the clock shows that region’s current time and UTC offset.
Does it work offline?
Yes. As a PWA it keeps ticking with no connection once loaded.
