We have 5 iPhones on our account and they all periodically move back an hour. When we turn them off and wait a few minutes, the time is correct when we turn them back on . We don’t live near a border that’s in a different time zone. It’s not daylight savings time. Our phones are set to ‘set automatically’ in the Date & Time settings. We live in a very rural area and I’m thinking the ONLY logical explanation it could be is that it has something to do with the cell towers. Please help.
