public class DateCache

extends java.lang.Object

Date Format Cache. Computes String representations of Dates and caches the results so that subsequent requests within the same minute will be fast. Only format strings that contain either "ss" or "ss.SSS" are handled. The timezone of the date may be included as an ID with the "zzz" format string or as an offset with the "ZZZ" format string. If consecutive calls are frequently very different, then this may be a little slower than a normal DateFormat.
