I need help figuring out a simple function (Work Start Time - Clock In
Time) = hours or minutes late

I tried...
B1-A1 = C1
8:40am - 9:00am = 23:40

I'm obviously missing something...please help!!

If you want it to be able to display negative time differences, then try:
Tools/ Options/ Calculation
and select 1904 date system.
