I want to calculate date difference in days, hours, minutes, seconds, milliseconds, nanoseconds. How can I do it?

推荐答案

假设你有两个 Date 对象s，您只需减去它们即可获得以毫秒为单位的差异:

Assuming you have two Date objects, you can just subtract them to get the difference in milliseconds:

var difference = date2 - date1;

从那里，您可以使用简单的算术推导出其他值.

From there, you can use simple arithmetic to derive the other values.
