TimeCalc 2000 is used for totaling payroll time cards and time sheets. TimeCalc 2000 goes far beyond the capabilities of its older time calculator sibling. It gives you the tools you need to perform advanced functions such as automatic overtime calculation, advanced break deduction, flexible reports, and many other features. While TimeCalc Classic can meet the needs of smaller businesses, those with more than a few employees will want to consider TimeCalc 2000 instead.
