I have to fix my iPhone clock time every few hours.

So I have to fix my clock time every few hours. It tells me it's 7:00 when It's 8:00. It's always an hour behind and I have to click "Set Automatically" to off and back on in "Date And Time" In the "General" Area of the settings. This fix works for a couple hours but I need a permanent solution.
