Select Display from the Time menu to display the Time Display window.

This window allows you to change the way TimeTracker displays the elapsed time.  When the display time is changed, the actual time entry is not altered, but rounded up to the nearest increment.  For example, if you clicked on 6 minute increments, and you work for 13 minutes, the time entry will display 18 minutes.  Decimal notation is only available for increments above 1 minute and for 100ths of an hour.

The best way to learn this is to click on an option and click the Apply button.  Clicking on the Apply button allows you to see the change.  Click OK to keep the change, or click Cancel to not make any changes.
