I need a formula to calculate the number of hours a truck has been
parked. There is a format already setup in excel that I must use.
There are 4 fiels Date In, Time In, Date Out, Time Out that the
formula must use to calculate the hours. The other catch is that they
pay no more than 10 hours a day. So in this scenario they parked
9/20/08 at 8pm and stayed till 9/25 at 3am the total hours would be 47.
