Richdave Posted February 26, 2010 Share Posted February 26, 2010 Every time I boot my OSX and then cold boot back to win, my clock is out EXACTLY 11 hours slow.. The BIOS clock seems to be changed when the OSX is booted or shut-down... not sure which?? The OSX clock is always perfect and the WIN clock is also perfect once reset... Any ideas?

srs5694 Posted February 27, 2010 Share Posted February 27, 2010 Yes. I've currently got computers running Windows XP, Windows Vista, and Windows 7 using this fix, and they all run fine. (I have seen some people complain that the time switches back after half an hour or so, but I've never seen this myself. I recommend you try it and if you have problems, deal with it then.)
