  Agreed, but for most programming it probably comes behind a portable way
to delete or rename files or scan a directory, for instance.  Certainly
    function To_UTC_Time (Local_Time : in Ada.Calendar.Time)
        return Ada.Calendar.Time;
would make sense in an Annex, so at least all implementations would look
the same.  But surely you then want to include function Day_Of_Week, leap
years, "+" and "-" with bigger than -86400.0 ..  86400.0 Duration and
adjusting for leap years and daylight savings, splitting into hours,
minutes, seconds, printing in various more or less standard forms, etc.
