PC-TimeClock (TM) keeps track of time you've spent on your computer. Time is charged to one or more "projects" by "punching in" when you begin work on each project; this data can then be used for client billing. Projects may be grouped into different "categories." For example, using "business" and "pleasure" categories will give you the percentage of time your computer was used for business purposes, which is needed to deduct computer costs as a business expense on your taxes.
