When using the automatic time tracking mode Complete Time Tracking can track the time that you are away from or not using the computer and ask you what work was done during this time.

For example: If you were working on the Energex Inc, Systems, Web Server category as shown in the screen shot above and left your computer to attend a sales meeting Complete Time Tracking would ask you what to do with the idle time when you return. You could then select to create a new time entry for a Sales Meeting category for the time that you were away from the computer, and to continue working on the Web Server category.
