The number of letters used in the pattern determines the format.
- Text: If the number of pattern letters is 4 or more, the full form is used; otherwise a short or abbreviated form is used if available.
- Number: The minimum number of digits. Shorter numbers are zero-padded to this amount.
- Year: Numeric presentation for year and weekyear fields are handled specially. For example, if the count of 'y' is 2, the year will be displayed as the zero-based year of the century, which is two digits.
- Month: 3 or over, use text, otherwise use number.
- Zone: 'Z' outputs offset without a colon, 'ZZ' outputs the offset with a colon, 'ZZZ' or more outputs the zone id.
- Zone names: Time zone names ('z') cannot be parsed.
- 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.
