DateFormatManager

public class DateFormatManager extends Object
Date format manager. Utility class to help manage consistent date formatting and parsing. It may be advantageous to have multiple DateFormatManagers per application. For example, one for handling the output (formatting) of dates, and another one for handling the input (parsing) of dates.
