 function Time_Of
     (Year    : Year_Number;
      Month   : Month_Number;
      Day     : Day_Number;
      Seconds : Day_Duration := 0.0)
      return    Time;

I don't see how Time_Of would be "using" some daylight savings time
algorithm unless that is what you fed it.

If your operating system is set to make daylight savings time adjustments,
you should change that setting.
