Description

us_dst_rules public static functions

  1.  
    (const date_type & d, const time_duration_type & td);
    Calculates if the given local time is dst or not.

    Determines if the time is really in DST or not. Also checks for invalid and ambiguous.

  2. bool (date_type d);
  3. date_type ( year);
  4. date_type ( year);
  5. time_duration_type ();
