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
