Online Clock with Milliseconds - Precise Live Time

✍ What is this tool?

This page provides a live online clock that shows the time down to the millisecond. Click the button to pause or resume it; every pause records the exact moment and keeps the 10 most recent pause times in a list. It is handy for ticket grabbing, flash sales or anything else that needs precise timing.

Note: the time comes from the operating system clock of the device running your browser. If that system clock is inaccurate, the displayed time will be inaccurate too.

This millisecond clock is built for people who need high-precision time display and capture β€” ticket grabbing, flash sales, exam timing, sports events and lab records, to name a few. No installation is required: open the page and it works. The interface is simple and the flow is straightforward. Press β€œPause” to capture the current instant, and the last 10 pause times are listed below so you can compare and look back at them.
The tool is implemented in plain front-end JavaScript and reads the local system time, so it keeps millisecond precision. All pause records are stored in your browser's local storage and are never uploaded to a server, which keeps your data private. It runs smoothly on Windows, macOS and mobile browsers, including Chrome, Edge, Firefox and Safari.
It is useful for students, teachers, developers, researchers, sports fans and anyone who needs accurate timing. The tool is free and there is no paywall β€” feel free to bookmark and share it. If you need a custom version or have suggestions, please reach out through the contact link at the bottom of the page.
Fullscreen mode: click β€œFullscreen” to open a minimal fullscreen clock that shows only a large time display β€” ideal for watching the time without distractions. In fullscreen you can hide the milliseconds, or hide every button and hint and keep only the digits. Click anywhere on the screen to leave fullscreen and return to this page.
