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

DateTime.minusDays介绍

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

The calculation will do its best to only change the day field retaining the same time of day. However, in certain circumstances, typically daylight savings cutover, it may be necessary to alter the time fields.

In spring an hour is typically removed. If subtracting one day results in the time being within the cutover then the time is adjusted to be within summer time. For example, if the cutover is from 01:59 to 03:00 and the result of this method would have been 02:30, then the result will be adjusted to 03:30.

The following three lines are identical in effect:

DateTime subtracted = dt.minusDays(6); 
DateTime subtracted = dt.minus(Period.days(6)); 
DateTime subtracted = dt.withFieldAdded(DurationFieldType.days(), -6);

This datetime instance is immutable and unaffected by this method call.
[中]返回此datetime减去指定天数的副本。
计算将尽最大努力只更改保留当天相同时间的day字段。但是，在某些情况下，通常是夏令时切换，可能需要更改时间字段。
在春天，一个小时通常被取消。如果减去一天导致时间在切换范围内，则将时间调整为在夏季时间内。例如，如果切换时间为01:59到03:00，且此方法的结果为02:30，则结果将调整为03:30。
以下三行实际上是相同的：

DateTime subtracted = dt.minusDays(6); 
DateTime subtracted = dt.minus(Period.days(6)); 
DateTime subtracted = dt.withFieldAdded(DurationFieldType.days(), -6);

此datetime实例是不可变的，不受此方法调用的影响。

DateTime today = new DateTime();
DateTime yesterday = today.minusDays(1);

Duration duration = new Duration(yesterday, today);
System.out.println(duration.getStandardDays());
System.out.println(duration.getStandardHours());
System.out.println(duration.getStandardMinutes());

private DateTime getSafeFirstCatalogEffectiveDate(@Nullable final DateTime input, final CallContext callContext) {
  // The effectiveDate for the initial version does not matter too much
  // Because of #760, we want to make that client passing a approximate date (e.g today.toDateTimeAtStartOfDay()) will find the version
  final DateTime catalogEffectiveDate = callContext.getCreatedDate().minusDays(1);
  return (input == null || input.isAfter(catalogEffectiveDate)) ? catalogEffectiveDate : input;
