I expect iOS 9 still has the post-iOS 4 behavior of doing an (s)NTP poll to time.apple.com at multi-day intervals. It happens rarely enough to be unpleasant to track but I have seen a ntpdate/sntp style poll from an iPad. A phone paired with a watch polls time.apple.com at least daily and does an NTP multi-packet exchange which would explain the relative accuracy. _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
