I have had my 2.66 MP for about 2 months now and it has started to forget the time upon reboot. It seems to just randomly pick some time about 4-8 hours in the past and I have to open the date and time settings to reset it. As soon as I open the preference pane it picks up the time server and fixes itself, but it is still very annoying. I once heard that the clock can start to go wrong if the battery inside the mac starts to die. I don't know if this holds true with the new MPs. Does anyone have any ideas?
