Have a 6s on Sprint. Last night I traveled an hour to another town. I noticed after I arrived the time on my iPhone was a hour behind (I did not cross a time zone). I restarted and it was fine. Now this evening it has done it again. I restarted it and initially it was behind, then it went to the correct time. I was planning to do the 9.1 update anyway so I did that and updated the carrier update for Sprint. Now an hour later the time is behind again. Everyone else in my household is also on Sprint and they're not having the same issue. I also realize that tomorrow morning at 2 am daylight savings time ends and then the time is suppose to be set back, not last night or right now. I'm thinking a daylight savings time bug? But shouldnt it go off the Sprint network? Anyone else with this issue?
