BootCamp clock issues

My guess is that the two operating systems don't recognize the system clock's settings for time zone. I would wager that the time zone variable is local within the operating system, hence, the setting isn't conserved between Windows and OS X. I am located in Eastern Standard Time (GMT -5) and unsurprisingly, the time is always 5 hrs in advance on my Windows side. Attempting to correct the time manually would be futile since that would change the system clock. This is the solution I found in another forum was the edit the Windows registry at:
and set it to a DValue of 1. I have yet to try this myself so good luck!
Code:
HKEY_LOCAL_MACHINE
SYSTEM
CurrentControlSet
Control
TimeZoneInformation
RealTimeIsUniversaland set it to a DValue of 1. I have yet to try this myself so good luck!

I tried it, but I can only go to Time Zone Information and I can not see Real Time Is Universal.

I've done this, and it's changed things such that Mac OS X always boots up with the correct time, as does Windows XP. However, after a while Windows sets the time forward by 7 hours. I've tried adjusting the time zone, but it has no effect. I can't keep Windows from setting itself 7 hours early. I live in the PDT zone.
i could not edit the registry. i got a "registry editing has been disabled by your administrator" which is funny, i thought i was the administrator of my computer.
Weird... Since booting in OS X seems to correct the startup time for XP, I tried unchecking the XP control box that tells the machine to sync to the internet, so that it would stop setting the clock forward by 7 hours. Yet XP still insists on setting it forward after a few minutes.
how do u get onto the windows registry?
hey guys.
Just wondering how do you go to the windows registry? how do you get there?

My windows time jumps forward as well after doing the registry hack. Is there a fix for this?

That's due to the Boot Camp time synching application. I haven't looked into it, but if you disable it, the time should be spot on. I don't know why Apple didn't use the registry key, to use UTC, and instead chose to use their shoddy time program.

What I did to fix this problem was to disable the automatic daylight adjustment in Windows. You can do this in the timezone settings when you double click on the clock in the taskbar.

Try removing it from your startup list using msconfig. However, like I said, I haven't looked into it.
That's right; this is a Boot Camp known issue. It's because of the different ways Windows and Mac OS X store and read the system time with respect to your time zone.
SOLUTION:
1 - set the realtimeisuniversal setting as described above.
2 - go into control panel -> administrative tools -> services (or "manage computer" and go to services) and select "apple time service". set this to be DISABLED and it won't change your clock again.
works fine 🙂

So, just one more time, doing the following procedure should stop my Mac partition's clock from moving backwards 4 hours every time I reboot back into OS X, right?
