Date.getTime（）不包括时间？ [英] Date.getTime() not including time?

问题描述

不明白为什么会发生以下情况：

Can't understand why the following takes place:

String date = "06-04-2007 07:05";
SimpleDateFormat fmt = new SimpleDateFormat("MM-dd-yyyy HH:mm");
Date myDate = fmt.parse(date); 

System.out.println(myDate);  //Mon Jun 04 07:05:00 EDT 2007
long timestamp = myDate.getTime();
System.out.println(timestamp); //1180955100000 -- where are the milliseconds?

// on the other hand...

myDate = new Date();
System.out.println(myDate);  //Tue Sep 16 13:02:44 EDT 2008
timestamp = myDate.getTime();
System.out.println(timestamp); //1221584564703 -- why, oh, why?

推荐答案

什么毫秒？您在第一个示例中只提供了几分钟的信息，而第二个示例从系统中获取当前日期，以毫秒为单位，您正在寻找什么？

What milliseconds? You are providing only minutes information in the first example, whereas your second example grabs current date from the system with milliseconds, what is it you're looking for?

String date = "06-04-2007 07:05:00.999";
SimpleDateFormat fmt = new SimpleDateFormat("MM-dd-yyyy HH:mm:ss.S");
Date myDate = fmt.parse(date);

System.out.println(myDate); 
long timestamp = myDate.getTime();
System.out.println(timestamp);
