From 11 AM to 6:30 PM is 7 Hours and 30 Minutes. Or subtracting 11
hours from 18 hours and 30 minutes leaves 7 hours and 30 minutes. Please
re-examine expectations.

I've created a simple worksheet to return the difference between two times,
however, the first time is being reported incorrectly by 2 hours.

B2 - 11:00
C2 - 18:30
D2 - =C2-B2

MS Excel 2007

The result of D2 is returned as 07:30, whilst this should read 05:30. This
problem does not happen with another cell.
Am I using some incorrect formula?
