Class DateCacheNoTick

  • public class DateCacheNoTick
extends java.lang.Object
    Date Format Cache. Computes String representations of Dates and caches the results so that subsequent requests within the same second will be fast. Only format strings that contain either "ss". Sub second formatting is not 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.
