Not to mention changing the BIOS time from UTC to local and back as you boot between OS's....
I configured my ThinkPad, so that Linux expects the hardware clock to be local time and configured Windows to not change anything. Works well enough.
I used to do just that, but moved completely away from localtime on Linux as Arch dropped support for it a couple of years back. There were technical reasons for doing so (which I've long since forgotten, but were sound) You have a registry hack on windows that allows it to use UTC, but it has side-effects on the windows side as well. I guess I'm just old-school and work with the UTC-5 and UTC-6 for daylight and standard time. That's generally why I have 14-days of uptime on Linux separated by 2 hrs of uptime on windows just to let updates apply. It's a bit of a pain swapping back and forth :)
Several years ago I changed Windows to expect UTC time on the CMOS clock and it works fine, and I haven't noticed any side effect. -- Cheers / Saludos, Carlos E. R. (from 42.2 x86_64 "Malachite" at Telcontar)
