本文整理了Java中org.joda.time.DateTime类的一些代码示例，展示了DateTime类的具体用法。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类的具体详情如下：
包路径：org.joda.time.DateTime
类名称：DateTime
[英]DateTime is the standard implementation of an unmodifiable datetime class.
DateTime is the most widely used implementation of ReadableInstant. As with all instants, it represents an exact point on the time-line, but limited to the precision of milliseconds. A DateTime calculates its fields with respect to a DateTimeZone.
Internally, the class holds two pieces of data. Firstly, it holds the datetime as milliseconds from the Java epoch of 1970-01-01T00:00:00Z. Secondly, it holds a Chronology which determines how the millisecond instant value is converted into the date time fields. The default Chronology is ISOChronology which is the agreed international standard and compatible with the modern Gregorian calendar.
Each individual field can be queried in two ways:
getHourOfDay()
hourOfDay().get()
The second technique also provides access to other useful methods on the field:
numeric value
text value
short text value
maximum/minimum values
add/subtract
set
rounding
DateTime is thread-safe and immutable, provided that the Chronology is as well. All standard Chronology classes supplied are thread-safe and immutable.
[中]DateTime是不可修改的DateTime类的标准实现。DateTime是ReadableInstant应用最广泛的实现。与所有实例一样，它表示时间线上的精确点，但精度仅限于毫秒。DateTime根据日期时区计算其字段。
在内部，该类保存两条数据。首先，它将日期时间保存为从1970-01-01T00:00:00Z的Java纪元开始的毫秒。其次，它保存一个年表，确定毫秒瞬时值如何转换为日期时间字段。默认的年表是等时法，这是商定的国际标准，与现代公历兼容。
可以通过两种方式查询每个字段：
