I had my iBook plugged in but it was turned off and I removed the battery (the big one, not pram). I unplugged the AC and then plugged it in again. I then powered up the system and my date was 1969 and the time was off. As a result forums I go to didn't show the proper posts and I couldn't check my email (excitemail).What do you mean by dates and times? If you remove the battery on the laptop it resets the dates in OS X only? and what other screwed up stuff can happen?
