In Windows, try this:
Run > RegEdit??
Find: HKEY_LOCAL_MACHINE > SYSTEM > CurrentControlSet > Control > TimeZoneInformation
??Add key ( REG_DWORD type ): RealTimeIsUniversal??
Double-click and set value to 1

I had the same problem and it is now gone after changing the Windows registry as suggested in the link above. OS X will reset the system time each time it boots and Windows picks it up thereafter.
Hope this works out for you.
