本文整理了Java中org.joda.time.DateTime.withZoneRetainFields()方法的一些代码示例，展示了DateTime.withZoneRetainFields()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。DateTime.withZoneRetainFields()方法的具体详情如下：
包路径：org.joda.time.DateTime
类名称：DateTime
方法名：withZoneRetainFields

DateTime.withZoneRetainFields介绍

[英]Returns a copy of this datetime with a different time zone, preserving the field values.

This method is useful for finding the millisecond time in another timezone. For example, if this instant holds 12:30 in Europe/London (ie. 12:30Z), the result from this method with Europe/Paris would be 12:30 (ie. 11:30Z).

The returned object will be a new instance of the same implementation type. This method changes the time zone and the millisecond instant to keep the field values the same. The returned object will be either be a new instance or this.
[中]返回具有不同时区的此datetime的副本，保留字段值。
此方法对于在另一时区中查找毫秒时间非常有用。例如，如果该瞬间在欧洲/伦敦（即12:30Z）保持12:30，则该方法在欧洲/巴黎的结果将为12:30（即11:30Z）。
返回的对象将是相同实现类型的新实例。此方法更改时区和毫秒瞬间，以保持字段值相同。返回的对象将是新实例或this。
