包路径：java.time.temporal.ChronoUnit
类名称：ChronoUnit

ChronoUnit介绍

[英]A standard set of date periods units.

This set of units provide unit-based access to manipulate a date, time or date-time. The standard set of units can be extended by implementing TemporalUnit.

These units are intended to be applicable in multiple calendar systems. For example, most non-ISO calendar systems define units of years, months and days, just with slightly different rules. The documentation of each unit explains how it operates.

Specification for implementors

This is a final, immutable and thread-safe enum.
[中]一组标准的日期周期单位。
这组单元提供基于单元的访问，以操纵日期、时间或日期时间。通过实现临时单元，可以扩展标准单元集。
这些单位适用于多个日历系统。例如，大多数非ISO日历系统定义年、月和日的单位，只是规则略有不同。每台机组的文件说明了其运行方式。
####实施者规范
这是一个最终的、不可变的、线程安全的枚举。
