/*! 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
