Rein Klazes d788e03057 Fixed TzSpecificLocalTimeToSystemTime and 
SystemTimeToTzSpecificLocalTime:
- take the time of day into the calculation, so the bias is calculated
  correctly during the transition days;
- the transition times are expressed as local time, not system time;
- correct the daylight logic for use on the southern hemisphere;
- beautify some LONGLONG arithmetic.
