This allows the packet to arrive at the cell site at the right point in time to be received in the correct time slot for the call. Some sites can have double width time slots and the arriving packet can slip into the extended time slot once the phone is at zero delay, giving a max dist of 70Km but capacity in that cell would be halved so it isn't done often. This delay figure in the phone is how they can triangulate where a phone is in TV shows. It's not just signal strength on GSM. I dunno where the cell tower is at Duck.
