    I don't know what's going on. When I'm working on Windows my current time is 2 hours too fast. When I synchronize it with NTP server it's ok for some time and then again 2 hours too fast.

    How to fix this ?

    I'm using Bootcamp 4.0 on Windows 7 64-bit Ultimate and Mac OS Lion.

    it's a BIOS emulation bug on older macs. no fix afaik. I also only think it happens on x64, not sure tho.

    oh yes, there has been some mindfkuc moments when you go about workign/gaming and realize clock is 2h forwards or backwards :rolleyes:

    It never happend. I don't what's going on. I'm using this Mac Pro more than a year. I remember it never happened on my old Mac Pro 2006.

    Check to see what time zone your Windows system thinks it's in.....

    I've got the same thing. I keep the WinXP partition offline, so it doesn't bother me too much. But if you take it online it autosyncs the clock and that messes with OSX clock upon reboot.

    Win clock is 2 hours behind. When synced it causes the OSX clock to be two hours ahead upon restart.

    Each operating system sets the machine's system clock when synchronizing
    with the network time server.

    Mac OS X sets it to UTC. Windows sets it to localtime. In your case I'm
    guessing that's Central European Summer Time (CEST) = UTC + 2 hours.

    I've started Mac OS Lion and synchronised the clock with NTP, the rebooted to Windows and the problem is gone so far.
