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

DateTime.<init>介绍

[英]Constructs an instance set to the current system millisecond time using ISOChronology in the default time zone.
[中]在默认时区中使用ISOChronology将实例集构造为当前系统毫秒时间。

private DateTime toDateTime(long instantNanos)
  {
    long millisSinceCreate = NANOSECONDS.toMillis(instantNanos - createNanos);
    return new DateTime(createTime.getMillis() + millisSinceCreate);
  }
}

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