27 /*! Class that provides format based I/O facet for date types.
28 *
29 * This class allows the formatting of dates by using format string.
30 * Format strings are:
31 *
32 * - %A => long_weekday_format - Full name Ex: Tuesday
33 * - %a => short_weekday_format - Three letter abbreviation Ex: Tue
34 * - %B => long_month_format - Full name Ex: October
35 * - %b => short_month_format - Three letter abbreviation Ex: Oct
36 * - %x => standard_format_specifier - defined by the locale
37 * - %Y-%b-%d => default_date_format - YYYY-Mon-dd
38 *
39 * Default month format == %b
40 * Default weekday format == %a
