Actually, the CDMA doesn't care what time it is, as long as they are all in sync. There are protocols for synchronizing the signal between phone, tower, main switches, and other networks. It just happens to be most convenient to use actual time from a fairly accurate source, and GPS is one way of doing it. You will find the CDMA time can be off a little at times, but major services, such as Verizon, try to keep it accurate. Craig
