两个日期之间有多少秒？ [英] How Many Seconds Between Two Dates?

问题描述

所以我有两个日期YYYY-MM-DD和ZZZZ-NN-EE

So I have two dates YYYY-MM-DD and ZZZZ-NN-EE

我如何知道他们之间有多少秒？ >

How can I find out how many seconds there are between them?

推荐答案

我正在服用YYYY& ZZZZ表示整数值，表示年份，MM& NN表示整数值，表示年份中的一年，DD& EE作为整数值，意思是每月的日期。

I'm taking YYYY & ZZZZ to mean integer values which mean the year, MM & NN to mean integer values meaning the month of the year and DD & EE as integer values meaning the day of the month.

var t1 = new Date(YYYY, MM, DD, 0, 0, 0, 0);
var t2 = new Date(ZZZZ, NN, EE, 0, 0, 0, 0);
var dif = t1.getTime() - t2.getTime();

var Seconds_from_T1_to_T2 = dif / 1000;
var Seconds_Between_Dates = Math.abs(Seconds_from_T1_to_T2);

以后参考的一个方便的来源是 MDN网站

A handy source for future reference is the MDN site

或者，如果您的日期使用格式javascript可以解析

Alternatively, if your dates come in a format javascript can parse

var dif = Date.parse(MM + " " + DD + ", " YYYY) - Date.parse(NN + " " + EE + ", " +ZZZZ);

然后您可以使用该值作为毫秒的差异（在我的示例中都有相同的意思）

and then you can use that value as the difference in milliseconds (dif in both my examples has the same meaning)
