  /*! Class that provides format based I/O facet for date types.
   *
   * This class allows the formatting of dates by using format string.
   * Format strings are:
   *
   *  - %A => long_weekday_format - Full name Ex: Tuesday
   *  - %a => short_weekday_format - Three letter abbreviation Ex: Tue
   *  - %B => long_month_format - Full name Ex: October
   *  - %b => short_month_format - Three letter abbreviation Ex: Oct
   *  - %x => standard_format_specifier - defined by the locale
   *  - %Y-%b-%d => default_date_format - YYYY-Mon-dd
   *
   * Default month format == %b
   * Default weekday format == %a
