历史 早期,Java 对时间和日期的使用往往重度依赖 java.util.Date 和 java.util.Calendar 。 可惜的是,这2个api 本身不够健壮,有类似线程不安全等诸多问题,于是乎2000年左右,市面上出现了很多用于处理时间类的框架,如Joda-Time。 在Java 8 时代 官方为JDK开发新的时间/日期API的进程:JSR-310,启动了。于是就出现了新一套健壮的API。 Roadmap 新的API Java 8 中 新的API 包括了 5个包 java.time java.time.chrono java.time.format java.time.temporal java.time.zone java.time 是基础包,里面包含了 时间 日期的 基础类 如 LocalDate, LocalTime等 java.time.chrono 有点像linux 的守护进程 chronyd 用来访问不同的时间服务器。 java.time.format 顾名思义用来格式化和转换日期时间 java.time.temporal 可能也想不出好名字吧,里面都是些底层扩展类 java.time.zone 用来对各时区的支持 1. 时间线 Java8中 引入了时间线的概念,时间是连续不断,抽象成一条线,线上的点表示某一时刻。 一班来说,这个设定主要是面对机器的
