public class UserDateFormatter
extends DateFormatter

UserDateFormatter is a subclass of DateFormatter which is responsible for parsing user date strings, i.e. string typed in or selected by the user. Additional natural language processing is done to make date input more user-friendly. The localized strings for "today", "tomorrow", and "yesterday" are recognized and converted to the appropriate date relative to the current date. Day of week strings (e.g. "monday", "sunday", etc.) are also supported for input.
