If there's nothing in either cell (cells are empty) the formula should
return 1, not an error. So, that tells me that the cells really aren't
empty.

The formula I posted accounts for *empty* cells.

In C1 enter:
=IF(B1A1,B1-A1,B1+1-A1)
and copy down. you should see:

16:00 0:30 8:30
15:43 23:49 8:06
13:55 0:01 10:06


We need B1+1 to push the time ahead to the next day (+24 hours)

In column C i want the time between A & B. But it keeps giving me
15:30
and it should be 8:30 Can anybody help.
The formula i am using is (B1-A1)
A is sign on time
B is sign off time
