MODE
Runs entirely in your browser
How it works
The page reads Date.now() when you open the Now mode and again every second, then shows the value in seconds (rounded down) and in milliseconds, with the same moment in UTC, ISO 8601 and your local time zone, labelled with its IANA name.
Processing runs in your browser
Timestamps are converted entirely in your browser tab. Our servers are not involved at any point.

Frequently asked questions
- How accurate is the timestamp?
- The timestamp is based on your system clock via JavaScript's Date.now(). It updates every second and is accurate to within a second under normal conditions.
- Can I pause the live update?
- The display keeps updating once a second. Click Copy next to a value to capture the value shown at that moment.
- Where is the timestamp in milliseconds?
- The Unix (ms) row shows the same moment in milliseconds, the value Date.now() returns, and its Copy button copies it.
- Does the page show the time in my time zone?
- Yes. Next to the timestamp the page shows the moment in UTC, as an ISO 8601 string, and in your local time zone, labelled with its IANA name such as Europe/London.
