java. util.Date. getTime 方法如何将给定的日期 & amp; 时间转换成长数?
Java API 文件说 - "返回自1970年1月1日,00: 00: 00格林尼治平时起的毫秒数, 由此日期天体代表" 。
感谢您的帮助。
查看"http://www.docjar.com/html/api/java/util/Date.java.html" rel="nofollow">Date.java 源代码。
您可以在最简单的案例中看到 Date 对象存储自1970年以来的毫秒数,而不是日期/时间等。
事实上,尽管Java API doc有明显明确的定义,但值得注意的是,报告的毫秒数并非自1970年1月1日00:00格林尼治平时以来实际物理毫秒数,或该物质的实际秒数。 实际上,人工插入的跳秒数是物理秒数加跳秒数 。
