I have Boot Camp on my iMac. When I go onto the Windows partition then come back to the Mac, the time is 7 hours behind. For example, if the time is actually 1:39 PM, the clock will show 6:39 AM. This causes Safari to not show websites. Even when I change the clock to the correct time, it still does not work until I close all Applications then open up Safari again. How can I prevent this from happening?
