HMSCalculate is an hour/minute/second calculator for the desktop — it is not officially sanctioned by the British Royal Navy. (Although, they should feel free to use it if they want.)

With HMSCalculate you can quickly and accurately add, subtract, multiply, and divide hours, minutes, and seconds. This can be very useful for time projections, totaling up timesheets, and analyzing efficiency. It's particularly suited to contractors, the self-employed, and anybody else who bills by the hour.

Because the interface is so flexible, you can mix and match decimal values (2.5 hours) with hour/minute/second values (02:30:00). Plus, a running total is always on display showing you your current totals in four useful formats: hours/minutes/seconds, hours only, minutes only, and seconds only. And, if you make a mistake, don't worry! HMSCalculate gives you the ability to view, edit, or delete any value at any point in your calculation without having to start all over again from the beginning.

HMSCalculate is available for Linux, Mac OS X, MS Windows, and a host of other OSes. To find out if it's available on your favorite OS, go to the downloads page. Or, to see what it looks like in action, check out the screenshots.
