CDMA mobile telephony needs system synchronization to +/- 10 uS in order to smoothly handoff a moving client from one cell to the next. Most systems use GPS to maintain this 10 uS. This says nothing about how bad it could get after that.

Any thoughts on what the likely accuracy of smart phone time
displays might be? I am thinking that the stacking of delays
along the path to its receive antenna plus any internal processing delays would accumulate to some unknown degree. Any thoughts on this?
