Question Clock

I had Windows XP on my computer and have since installed Mandrake 9.2.

During the install I had to set the time / timezone information which I did. The problem I have is that when I booted up Windows the time had changed by several hours so I corrected it. Then when I boot up Mandrake the time has been changed by the same number of hours. So I corrected it in Mandrake. But when I boot up Windows....I think you can see the problem.

How do I get round this?

I think you're changing your bios clock instead of the way your OS reads it. Windows reads the bios time. It's easy to miss the option in an initial setup, but mandrake asks if your system time is based on local time or GMT. If you select GMT when setting the time, it offsets the clock by whatever your timezone difference is. There are a number of scenarios you can imagine, but basically, you're telling Windows to read your bios one way, and Linux to read it another way.

So, to get it correct, you'll need to run whatever timezone program you use, and make sure this option is set the same way in both OSs. In control center/system, you can adjust your clock. After you pick your timezone, it will ask you if your bios is set for GMT or local time. In windows, make sure your settings are similar.

Thumbs up

OK Got it

The clock in BIOS was set to the local time here in HK. When I set the time in Mandrake, I put in the local HK time and entered it. A window popped up asking if my clock was set to GMT. Previously I had put yes - I put in 'no' this time and it worked. Having come from the UK originally, this is a mistake easily made as obviously the time is GMT.

Thanks for your help
