Elapsed Time Recorder



This page acts like a stopwatch. It runs entirely on your computer, so does not require an internet connection to run.
Click on any of the links at the top of the page to reveal (or hide) more information about this online tool.


If you are reading this paragraph, then you probably don't have JavaScript installed/enabled on your computer.
At this point in time the calculators on this site are entirely dependent on JavaScript. Given enough time and money it is hoped to develop a version in the future which will be able to operate independently. Since JavaScript runs on your own computer, rather than on this server, it has been possible to set up this site much more quickly than if a server-side language was used, and it is possible to serve far more pages with the available bandwidth.
