I have a timesheet that allows employees to enter their start and end times
in regular time format. The current formulas then add up the amount of time
actually worked wich is also deleivered in regular time format.

Employees get an extra amount of money for working late night hours, so I
would like to figure their time separately. For example they worked a total
of 4:45 at (4h 45m) at the regular wage and then 2:00 (2h 0m) at the higher
rate time.

In essence Excel will have to look at the start and end times and determine
if they fall between the "late night hours" then add the two times separatley.

Any ideas? Is this even possible?
