    My macbook pro 2.33ghz 17" keeps booting up with the wrong time (this happens too in bootcamp under windows). Any recommendation on how to repair this? I have an applecare warranty, but if its a simple repair I would rather avoid the headake.

    When I connect to the internet the time corrects itself.

    This is an inherent flaw in dual-booting between Windows and OSX.

    sweet, good to know and thank you for the fast reply. Thinking about it now it does seem this only became an issue after dual booting. Just wondering, do these macbook pro's have an internal clock battery like old computers had?

    They have an internal clock, yes. Windows uses a different means of setting the hardware clock than OS X/Linux/BSD/basically everyone else, and every time you boot into Windows, Windows resets the hardware clock as it sees fit, without regard to any other OSes you might have installed.

    So when you switch out of Windows, the clock's time value is no longer accurate. It's normal behavior--OS X should check the time and update accordingly after a few minutes, unless you've disabled the check, in which case you'll have to set it manually or use a different fix.
