An example of a punch in at 8:00 am and punch out at 5:00 pm is: Hours = 17, click Ending Time; Hours = 8, click Starting Time. That will display 9:0:0, indicating 9 hours worked. However, if a 30 minute lunch was taken, click Zero Entries, then enter 30 in the minutes box and click Deduct Time. The new value displayed is 8:30:0, indicating 8 hours, 30 minutes worked.
An example of a shift spanning from 10:00 pm to 6:00 am is done in two steps. They are: Hours = 24, click Ending Time; Hours = 22, click Starting Time. That will display 2:0:0. Then, click Zero Entries followed by Hours = 6, click on Ending Time; Hours = 0, click on Starting Time. That will display 8:0:0, indicating a total of 8 hours. Although this is designed as a daily time card calculator, it will handle a span of one or more days in the total accumulator.
