GMT clock time probelm in Dual boot?

[Muhammad Adnan Asim]

Hi everyone,

 

I am running dual boot of windows 7 and snow leopard 10.6.3 on my dell studio 1555.

 

Clock time is not correct in mac. If i fix the clock time in mac then clock time mess up in windows 7.

 

so at the moment in mac, clock is one hour ahead, this way in windows 7 clock time does not mess up.

 

Is there any solution that i could fix the clock time in both OS.

It has to do i believe because windows saves the time as current local time, and mac saves it as current gmt time and then uses the os to change it to local time. You can set your time zone in windows to gmt and i believe it will be fine. It worked when i used to dual boot leopard and win xp.

"Compiling from the above:

 

1) Upon successful installation / setting up of OSX (choosing your time zone), it will change BIOS time to UTC, leave it.

 

2) OSX should display the local time correctly upon reboot, but Windows doesn't.

 

3) To fix Windows time error, launch Regedit.

 

4) Go to:

 

- HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\TimeZoneInformation

 

5) Right click and create a new DWORD entry "RealTimeIsUniversal"

 

6) Set the value to 1.

 

6) Upon reboot, Windows should show the correct local time. "

 

 

That should do the trick.
