Has anybody else observed this with their iPhone since “upgrading” to iOS 9? 
Anyone know of any difference in the reference time ( e.g. GPS vs. network 
time) that Apple is using to “dumb down’ their smartphones in favor of Apple

Yes, on one quick check, I now see an accuracy (or rather error) o my iPad 
of up to several seconds (iOS 9.0.2) compared to my recollection of 
sub-second accuracy under iOS 8.0.2x.

My £50 Windows 10 tablet using real NTP does /much/ better!
