if you've flashed to a 6.5 rom, that is correct. If you never press on the clock , it will never mess up. However if you press the clock in touchflo, then it forever will go ahead an hour. It happens in every 6.5 rom, and to my knowledge, has not been fixed. But there are ways arround it. If you download GAlarm, it has the fix. as soon as you open it, it will tell you your device has the timezone bug, and a soft reset is required to fix it. the second option is to download wmbroultimate theme. Its over at smartphonejunkie I know. It opens call history by hitting the clock button. Making it a little easier to stay away from the clock. Option c= check out this thread.
