and just in addition...

if you format a3 as a number, multiply it by 24, =(a2-a1)*24, just in case
you want to figure out an hourly wage, for example.

Direct subtraction should work if you tell Excel that the times are for
different dates:
In A1, A2:

9/11/05 11:00 PM
9/12/05 7:00 AM

In A3 put:
=A2-A1 and format as hh:mm and you will see:

8:00

11:
p.m. to 7: a.m. Normal calculations won't work in this case.
