本文整理了Java中org.joda.time.DateTime.minusHours()方法的一些代码示例，展示了DateTime.minusHours()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.minusHours()方法的具体详情如下：
包路径：org.joda.time.DateTime
类名称：DateTime
方法名：minusHours

DateTime.minusHours介绍

[英]Returns a copy of this datetime minus the specified number of hours.

The calculation will subtract a duration equivalent to the number of hours expressed in milliseconds.

For example, if a spring daylight savings cutover is from 01:59 to 03:00 then subtracting one hour from 03:30 will result in 01:30. This is a duration of one hour earlier, even though the hour field value changed from 3 to 1.

The following three lines are identical in effect:

DateTime subtracted = dt.minusHours(6); 
DateTime subtracted = dt.minus(Period.hours(6)); 
DateTime subtracted = dt.withFieldAdded(DurationFieldType.hours(), -6);

This datetime instance is immutable and unaffected by this method call.
[中]返回此datetime减去指定小时数的副本。
计算将减去一个与以毫秒表示的小时数相等的持续时间。
例如，如果春季夏令时切换时间为01:59到03:00，则从03:30减去一小时将得到01:30。这是一个提前一小时的持续时间，即使小时字段值从3更改为1。
以下三行实际上是相同的：

DateTime subtracted = dt.minusHours(6); 
DateTime subtracted = dt.minus(Period.hours(6)); 
DateTime subtracted = dt.withFieldAdded(DurationFieldType.hours(), -6);

此datetime实例是不可变的，不受此方法调用的影响。
