I'm running a tri-boot setup with Windows 7, ubuntu 12.04, and Backtrack 5 all running on separate partitions. When ever I boot into windows after linux the time is all messed up and I have to manually reset it. The same happens the other way around. How do I fix this?

That's because Windows doesn't do UTC. Refer to this.

Thanks! In your opinion, what do you think would be better, making windows UTC or Linux local? – redIago Jul 19 '12 at 6:24
UTC is the better way to go ;) – Rinzwind Jul 19 '12 at 6:51

Changing Linux to use local time is easier and more reliable than changing Windows to use UTC, so dual-boot Linux/Windows systems tend to use local time.

This is mentioned in the link provided. So I guess we have to make Ubuntu use hardware clock as local time.
