Thanks to this system, if the GM didn't choose to apply some sort of common sense (and mine didn't), it was possible to end up with a negative number for the total number of hours your trip was going to take. Ergo, you arrived before you left. My GM knew we would cause trouble with this, but he allowed it anyway (he's a very permissive GM, perhaps too much so).
