So as of today, day light saving time ends. But my phone would not change time automatically. I went in to Date and Time, the time zone seted to GMT+4 which is wrong. Ontario suppose be GMT-5. I rested the time zone, however, each time I unlocking the iPhone, the time zone will automatically rest back to GMT+4 for some reason. Is there anyway preventing this happening? I just want the time right. UPDATE: I have tried to restart the phone, rest all settings, Turing the airplan mode on made sure location service is on. The phone will revert back to wrong time zone in 5 seconds.
