+1 that might just force it to keep it's settings

It didn't work. Still lost the hour on a couple of reboots today. Only happens in 7 as I said. Vista and OSx86 are both fine.

I had the same problem in a tripple boot config. When I boot into xp, it was fine, when I went back into 7, it was an hour off. For me... It was one of the OS's not being set to adjust for daylight savings, but had to do one more step...

After correcting the setting, I booted into each OS then right after each boot, would go into the bios, when I came across wrong time in bios, I reset the time in the bios, not in the OS. Think the main thing is to not correct it in the OS, but in the bios. If you boot into OS and time is wrong, just exit and enter bios to correct.

OK, I tried that, but it has made no difference. All 3 OSs have the time set correctly, but something is changing it when I boot back into W7.

Have you checked the event log straight after boot to see if anything is listed? Might be an idea

Windows 7 RC 7264

ive had this before when booting between windows and osx86/linux.

try adding the following DWORD to the registry and set the value to 1 and you have completely fixed the situation.
Don’t forget the value change to 1 then reboot.

Youll probably need to do the same in Vista as I suspect booting to osx86 is causing the time to be set to universal time, then when u go back to windows vista or 7 its using local time and is then 1 hour out.

Perhaps you have only noticed it wrong in windows7 because of the order you have booted to each OS. e.g.

Boot to Osx86 (time gets set to UTC)
Boot to Windows7 (time is now wrong by 1 hour, you then manually fix it)
Boot to Vista (time is correct because you have already fixed it in windows 7)

Try booting osx86 then windows vista directly after and see if vista is out too.
