Unlike Excel, Access has no number format for displaying cumulative time. But it can calculate times over 24 hours without problems. The key to understanding how it works is that dates and times are stored with 1 day (24 hours) as unit. So 6:00 is stored as 0.25 and 15:00 as 0.625. If you multiply a time by 24, you'll get the number of hours, but you must display it as a number, not as a time.
