I do not believe that ntpd will adjust the clock for you when the time is off by more then 1000 seconds. (16 and 2/3rd minutes.) The problem with duel-booting and having the clock in local time is that the system has no way to tell if the other OS has already corrected for the time change. If the clock is set to UTC, then this is not a problem because only the local time changes, and not the system clock.
