包路径：org.threeten.bp.LocalDateTime
类名称：LocalDateTime
[英]A date-time without a time-zone in the ISO-8601 calendar system, such as 2007-12-23T10:15:30.
LocalDateTime is an immutable date-time object that represents a date-time, often viewed as year-month-day-hour-minute-second. Other date and time fields, such as day-of-year, day-of-week and week-of-year, can also be accessed. Time is represented to nanosecond precision. For example, the value "2nd October 2007 at 13:45.30.123456789" can be stored in a LocalDateTime.
This class does not store or represent a time-zone. Instead, it is a description of the date, as used for birthdays, combined with the local time as seen on a wall clock. It cannot represent an instant on the time-line without additional information such as an offset or time-zone.
The ISO-8601 calendar system is the modern civil calendar system used today in most of the world. It is equivalent to the proleptic Gregorian calendar system, in which today's rules for leap years are applied for all time. For most applications written today, the ISO-8601 rules are entirely suitable. However, any application that makes use of historical dates, and requires them to be accurate will find the ISO-8601 approach unsuitable.
This class is immutable and thread-safe.
[中]ISO-8601日历系统中没有时区的日期时间，例如2007-12-23T10:15:30。
LocalDateTime是一个不可变的日期时间对象，它表示一个日期时间，通常被视为年-月-日-小时-分-秒。还可以访问其他日期和时间字段，例如年中的日期、周中的日期和周。时间表示为纳秒精度。例如，值“2007年10月2日13:45.30.123456789”可以存储在LocalDateTime中。
此类不存储或表示时区。相反，它是对日期的描述，用于生日，与挂钟上显示的当地时间相结合。如果没有诸如偏移量或时区之类的附加信息，它不能表示时间线上的某个瞬间。
ISO-8601日历系统是当今世界大部分地区使用的现代民用日历系统。它相当于公历的前身，即今天的闰年规则在任何时候都适用。对于今天编写的大多数应用程序，ISO-8601规则完全适用。然而，任何使用历史日期并要求其准确的应用程序都会发现ISO-8601方法不合适。
####实施者规范
这个类是不可变的，并且是线程安全的。

* From http://stjarnhimlen.se/comp/time.html:
*
* TAI (Temps Atomique International or International Atomic Time) is
* defined as the weighted average of the time kept by about 200
* atomic clocks in over 50 national laboratories worldwide.
* TAI-UT1 was approximately 0 on 1958 Jan 1.
* (TAI is ahead of UTC by 35 seconds as of 2014.)
*
* GPS time = TAI - 19 seconds. GPS time matched UTC from 1980-01-01
* to 1981-07-01. No leap seconds are inserted into GPS time, thus
* GPS time is 13 seconds ahead of UTC on 2000-01-01. The GPS epoch
* is 00:00 (midnight) UTC on 1980-01-06.
* The difference between GPS Time and UTC changes in increments of
* seconds each time a leap second is added to UTC time scale.
