When the main battery runs flat, the Macbook Pro loses the internal clock and gets reset back to year 2000. Together with the clock issue, it can no longer connected to the WPA2 network, whose password should be saved in Keychain. Therefore, NTP cannot obtain correct time. To fix this problem, I have to go to Keychain, delete the entry for my WPA2 Wi-Fi SSID, then enter the WPA2 password when connecting to the network, and then reboot the Macbook Pro for this password to stick. Otherwise, every time I try to disconnect from the WPA2 Wi-Fi network and then reconnect to it, I am prompted to re-enter the WPA2 password. It also appears that my wife's iPhoto-to-Facebook integration got screwed up after the Macbook Pro's battery ran flat. I guess I have to call Apple Care to get this fixed.

Lose wifi-key and time reverts to march 2001. Annoying, coz all my iCal alarms start ringing once reset! Have the same prob with my 2009 MBPro. Lose wifi-key and time reverts to march 2001.

My macbook is only a couple months old (basic 2009 Macbook) and if I ignore the low battery warning and let it run until it totally shuts down it will oftentimes (but not everytime) wipe out not only the clock, but my network password as well. (Not sure why the password gets lost due to the battery...strange). Hard to believe Apple dropped the use of a 10-year coin cell battery (that costs under $1 retail) and instead went with a capacitor or even a rechargeable battery. Obviously it was a very bad idea. Apple may be the king of innovation, but sometimes they should stick with things that are known to work quite reliably. I have the same issue.
