I keep having to set my clock on my computer. If I set it so that it's UTC -6:00, the next time I turn on my computer, it's 6 hours ahead of the real time. So I change the time zone to UTC -12:00 and the next time I get on my computer, it's 6 hours behind. I've tried changing the time instead of the time zone, but it just switches back to using the time zone I have set instead of the time I have set next time I turn on my computer. This has been going on for a long time. Help?
