    Hey Everyone,
    I have noticed that if I have my mac turned off, and I end up turning it back on in an area where I donot have internet. The time is wrong, it seems to stay the time it was the last time I had the computer on. I don't know if Windows does the same thing, but I am pretty sure it doesn't do this.

    Also, when I noticed this I was booting in Mac OS X after using Bootcamp. Maybe this has something to do with this. Does anyone know whether it is necessary to have an internet connection to still have the correct time? Why doesn't it just remember what the time was last time and keep it the same?

    Thanks for any help.

    Sounds like a dead CMOS battery. Apple should replace it under warrenty for free.

    It's a known issue with bootcamp. It will happen after you reboot from being in Windows through bootcamp.

    Ok, hoping its a bootcamp thing. As if the CMOS Battery is dead.... I'll be returning the macbook, I only bought it a month ago. Hope it's just bootcamp.

    Yes, this is a known issue, however, there is a little Windows registry hack you can use to fix it. Note that this change has to be done on the Windows side, and may not stick, as noted in the article.
