i have the same 'problem'.
soooooooo...just outta curiousity, i can't get my system clock to set correctly. it's always an hour off, i think because the time zone changed recently where i am and maybe DST issue too. i think it's maybe conflicting with the NTP servers info i'm getting.
are your system clocks off by any chance? is so, when i get back to the office i might set my clock manually and turn off ntp.
