Deserted Posted November 5, 2010 Share Posted November 5, 2010 Hi guys, having been lumbered with vista for a few years. I recently installed Ubuntu, since I have a partitioned hard drive. Have to say I'm very impressed with but there's one thing that keeps occurring which I don't understand. Whenever I switch between operating systems it moves my clock back three hours. Since I'm also three hours ahead of GMT, I'm sure there must be a reason for this. I know my way around my laptop quite well and have had a good look but cannot find a solution to this issue. Any thoughts and help are greatly appreciated. Link to comment Share on other sites More sharing options...

Jumbo chilli Posted November 5, 2010 Share Posted November 5, 2010 I had the same problem before and found the solution elsewhere. Credit goes for "insanelymac.com". Here you go. "The short solution for people who know how to edit the registry: A DWORD key called HKEY_LOCAL_MACHINE\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: HKEY_LOCAL_MACHINE\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." I copy-and-pasted above info. Cheers.
