PolyglotDateTimeLocalizer
Specialization of PolyglotValueLocalizer that allows to localize a date/time value T and returns a simple String.
A date/time value is anything component or set of components that may appear in a full date time localization (e.g. year, minute of hour, time zone, day of the week, etc.)
Note that any class implementing this interface is not strictly required to return the same exact string for the same value in different platforms.
