public class FastDateFormat
extends java.text.DateFormat

Fast date formatter that caches recently formatted date information and uses it to avoid too-frequent calls to the underlying formatter. Note: breaks fieldPosition param of format(Date, StringBuffer, FieldPosition). If you care about the field position, call the underlying DateFormat directly.
