Not sure how you have your sheet set up, but try this: With your Start Time in A1 and your End Time in B1

A B 1) 09:15:00 02:00:00In cell C1 enter the formula:

=IF(A1>B1,B1+1-A1,B1-A1)

Since B1 is the next day, you need to add 1 to get the correct time.

Don't forget to format cell C1 as Time

For a very good in depth explanation of how to do TIME Math in Excel see here:
