/**
 * DateFormat class.
 *
 * The DateFormat class allows you to format dates and times with
 * predefined styles in a locale-sensitive manner. Formatting times
 * with the DateFormat class is similar to formatting dates.
 *
 * Formatting dates with the DateFormat class is a two-step process.
 * First, you create a formatter with the getDateInstance method.
 * Second, you invoke the format method, which returns a string containing
 * the formatted date.
 *
 * DateTime values are formatted using standard or custom patterns stored
 * in the properties of a DateTimeFormatInfo.
