Timesheet Calculator

I wrote the timesheet calculator to help speed up the filling in of company timesheets. It allows input in several formats - hhmm, hh:mm or a decimal notation, and doesn't requre minutes to be entered. It shows the amount of time you've spent at your desk during a day, any overtime worked, and sums for the week. It also outputs the duration in several different formats.

It's written for the web in JavaScript, and should work on most browsers. If cookies are enabled on your browser, it will remember your preferred day length and lunch duration.
