如何比较日期和时间并获取差异，然后在Javascript中将其设置为秒

Question

如何比较这两个日期呢?

Event Date: May 25, 2015 02:00:00

，第二个日期将是客户端日期，例如:May 20, 2015 05:00:00我的目标是得到它的差异，把它转换成秒。

Answer 1

var t1 = new Date(2015, 05, 25, 2, 0, 0, 0)
var t2 = new Date(2015, 05, 20, 5, 0, 0, 0) 
var diff = t1.getTime() - t2.getTime()
var secondsFromT1ToT2 = diff / 1000;
var secondsBetweenDates = Math.abs(secondsFromT1ToT2);
console.log(secondsBetweenDates)
# 421200
