How to fix time changing in boot camp to mac osx

Question

After I installed Windows 7 Ultimate with boot camp on my 2011 Macbook Pro I installed the drivers from the disc and installed all the updates from software update in windows 7.
Whenever I restart into Mac OSX 10.6.8 it will change the date to the next day (or about 11 hours) and even if the automatic time set from the internet is selected it will still say this is the correct time
So i change it manually and keep it this way. But then again whenever I restart into W7 it will change back to a different time
I have had a look at this forum but with the last suggestion on the page but there was no file specified to delete

Thanks and I hope i can get this fixed in a couple of days!
I might have to go into the apple genius bar if i cannot get it fixed online

As you've learned the hard way, if you were expecting an instant answer to a problem or technical question, you won't often find it here unless many other people are encountering the issue at the same moment on the same day. If no-one currently online when you post your message has encountered your specific issue or problem and been able to remedy it, you're unlikely to get an immediate response. 
In the less-active areas of these forums, questions often linger 24 hours or more before receiving a response, and many questions go unanswered far longer. That is because these are free user-to-user forums, not a paid tech support help line.
And yet, some wonderful people spend an extraordinary amount of time here being helpful: Take a look at the list of Top Participants in any Community. It is based upon reputation points. It takes decades of determined effort to achieve a 'Level 10' status!
I've been a casual user here for almost four years, and I'm barely a 'Level 3' which begins at 500 reputation points, equating to as few as 50 'correct' or as many as 100 'helpful' answers, so take any advice I've posted within these forums at your own risk.
Not being one to assume that any totally frustrated user actually searches far and wide within or outside these forums for answers, or even understands how to use the forum search feature before getting frustrated, I'll offer some links that could still be helpful...
The Boot Camp time sync issue goes back to at least 2007-2008, which predates both OS X 10.6 and Windows 7.  A popular search engine will provide quite a number of off-forum links that may or may not be helpful.
This old link within Apple Support Communities provides a couple of off-site Microsoft links to instructions for setting the system clock and synchronizing with an internet time server.  It does not specifically address OS X 10.6 and Windows 7, but OS X 10.5, Windows XP and Windows Vista: http://support.apple.com/kb/TS1285
Note that you must have an active internet connection for time-sync to work properly. 
Have you set up your network connection(s) on the Windows 7 side?
Which time zone have you selected on the Windows side?
Which internet time server(s) are you using on OS X and in Windows?
This off-site post suggests using regedit in Windows to disable the Apple Time Service in Windows.

May that future responses to your questions within the Apple Support Communities be, uh, somewhat more timely.
