Text: 4 or more, use full form, <4, use short or abbreviated form if exists. Number: the minimum number of digits. Shorter numbers are zero-padded to this amount. Year is handled specially; that is, if the count of 'y' is 2, the Year will be truncated to 2 digits. Text & Number: 3 or over, use text, otherwise use number. Any characters in the pattern that are not in the ranges of ['a'..'z'] and ['A'..'Z'] will be treated as quoted text. For instance, characters like ':', '.', ' ', '#' and '@' will appear in the resulting time text even they are not embraced within single quotes. A pattern containing any invalid pattern letter will result in an exception to be thrown during formatting or parsing.
