33 | * This class allows the formatting of dates by using format string. | |
34 | * Format strings are: | |
35 | * | |
36 | * - %A => long_weekday_format - Full name Ex: Tuesday | |
37 | * - %a => short_weekday_format - Three letter abbreviation Ex: Tue | |
38 | * - %B => long_month_format - Full name Ex: October | |
39 | * - %b => short_month_format - Three letter abbreviation Ex: Oct | |
40 | * - %x => standard_format_specifier - defined by the locale | |
41 | * - %Y-%b-%d => default_date_format - YYYY-Mon-dd | |
42 | * | |
43 | * Default month format == %b | |
44 | * Default weekday format == %a | |
