在我们对 Joda 日期对象进行转换的时候，我们需要将 joda 设置时区，这样才能针对不同的时区输出正确的日期格式。
时区的设置是在：
logger.debug("dateTime for EST is - [{}]", dateTime.toDateTime(DateTimeZone.forID("America/New_York")));
中的方法 DateTimeZone.forID 方法中进行设置的。
这个方法使用的参数是字符串，因此你需要定义你需要的字符串。
时区字符串
时区字符串从哪里来呢？
请参考下面的链接：https://www.joda.org/joda-time/timezones.html
可以参考的字符串可以从上面的链接中找到。
你也可以参考下面的表格，找到你需要设置的时区。
