比较两个时间的差值

var sub1 = Math.abs(endDate - beginDate);
//			var day = Math.floor(sub1/(1000*60*60*24));
			var hour = Math.floor(sub1/(1000*60*60) % 24);
			var min1 = Math.floor(sub1/(1000*60) % 60);
			var sec = Math.floor(sub1/1000 % 60);
//			if (day >= 1) {
//				s = day + "天";
//			}
			if (hour >= 1) {
				s += hour + "小时";
			}
			if (min1 >= 1) {
				s += min1 + "分";
			}
			if (sec >= 0) {
				s += "秒";
			}
