Question

I got my macbook yesterday. Next to the problems I've heard before,today I found that the time for MAC OS is always 8 hours before the time in Windows XP no matter how I adjust the time zone. I've tried many ways, but found no way out. Is there somebody else can give me some tips. Tks!

Why is the time different between Mac OS X and Windows XP on my computer?
The Windows XP and Mac OS X operating systems handle your computer's date and time information differently, so the date and time may be different when you switch operating systems. For best results, use a network time server and resync the date and time whenever you switch operating systems. In Mac OS X, use the “Set date & time automatically” option in the Date & Time preferences. In Windows XP, click the Update Now button in the “Date and Time Properties” control panel.
Nice solution

"I found a better solution to this whole thing. The problem with the Windows clock being off is because the hardware clock (the one on your actual motherboard) is being set to "Universal" time, or GMT, when you shut down your MacOS bootup. When you boot Windows, Windows assumes your clock is set to your local timezone because that's what Windows does by default. This explains why the people who set their MacOS clock to GMT got the right time in Windows... If the hardware clock is being set to "GMT," when it's actually the local time, Windows will pick this setting up as local time as it did before.
To fix this, you need to add a key to your Windows system registry to tell Windows that your hardware clock will always be GMT.
* WARNING: Editing your registry improperly can render your Windows installation inoperable. Proceed VERY carefully. I am not responsible if you mess something up. *
The short solution for people who know how to edit the registry:
A DWORD key called HKEYLOCALMACHINE\SYSTEM\CurrentControlSet\Control\TimeZoneInformation\RealTimeIsUniversal needs to have the value of "1"
The step-by-step solution is as follows:
1. Boot Windows
2. Click Start --> Run and type regedit. Click OK
3. The Windows Registry Editor should pop up. Navigate within the explorer to:
HKEYLOCALMACHINE\SYSTEM\CurrentControlSet\Control\TimeZoneInformation
4. Click on the TimeZoneInformation "folder" from the navigation pane if you haven't already done so.
5. This assumes the correct key doesn't exist. If it does, you will just change the existing key's value: Right click on the white space within the folder (If you don't have a right mouse button, you may need to download a program called applemouse to emulate the "control-click" of the apple 1-button mouse). Select new --> DWORD Value. Title the key "RealTimeIsUniversal" (No quotes). Set the value to "1" (No quotes again). Hexidecimal should be fine.
6. Either reboot and set the clock in MacOS or set the clock in Windows. You should now be able to reboot into either OS and have a correct clock."
