/**
 * A field that will contain a date and/or time
 *
 * Currently recognizes only {YYYY}-{MM}-{DD}T{HH}:{MM}:{SS.S*}Z formatted dates.
 *
 * Besides the parameters recognized by HTMLTextField, additional recognized
 * parameters in the field descriptor array include:
 *  type - 'date', 'time', or 'datetime'
 *  min - The minimum date to allow, in any recognized format.
 *  max - The maximum date to allow, in any recognized format.
 *  placeholder - The default comes from the htmlform-(date|time|datetime)-placeholder message.
 *
 * The result is a formatted date.
 *
 * @note This widget is not likely to work well in non-OOUI forms.
