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.

Hello, Time-nutters--

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?
