Java 日期时间处理类库，Joda-Time v2.9.1 发布
jopen 9年前
JodaTime 提供了一组Java类包用于处理包括ISO8601标准在内的date和time。可以利用它把JDK Date和Calendar类完全替换掉，而且仍然能够提供很好的集成。
Joda-Time主要的特点包括：
1. 易于使用:Calendar让获取"正常的"的日期变得很困难，使它没办法提供简单的方法，而Joda-Time能够 直接进行访问域并且索引值1就是代表January。
2. 易于扩展：JDK支持多日历系统是通过Calendar的子类来实现，这样就显示的非常笨重而且事实 上要实现其它日历系统是很困难的。Joda-Time支持多日历系统是通过基于Chronology类的插件体系来实现。
3. 提供一组完整的功能：它打算提供 所有关系到date-time计算的功能．Joda-Time当前支持6种日历系统，而且在将来还会继续添加。有着比JDK Calendar更好的整体性能等等。
