AttributedCharacterIterator returned
 from DateFormat.formatToCharacterIterator and as
 field identifiers in FieldPosition. | 
DateFormatSymbols
DateFormatSymbols is a public class for encapsulating
 localizable date-time formatting data, such as the names of the
 months, the names of the days of the week, and the time zone data. |
