    <script>
           var timestamp3 = new Date().getTime();//当前时间的时间辍
           var date = new Date();
           var year = date.getFullYear();
           var month = date.getMonth()+1;
           var day = date.getDate();
           var hour = date.getHours();
           var minute = date.getMinutes();
           var second = date.getSeconds();
           var up = second*1000 + minute*60*1000 + hour*60*60*1000 ;//当前时间之前的时间辍
           var down = 86400000 - up;     //当前时间之后的时间辍
	   layui.use('laydate', function datatime(){
		    var laydate = layui.laydate;
	        var start = laydate.render({
	        elem: '#start_time',
	        type: 'datetime',
	        value: new Date(timestamp3-up),
	        calendar: true,
           done: function(value, date, endDate){
           	end.config.min = {
                       year: date.year,
                       month: date.month - 1,
                       date: date.date,
                       hours: date.hours,
                       minutes: date.minutes,
                       seconds: date.seconds
                   }
           	}
   });
	    var end = laydate.render({
		  elem: '#end_time',
		  type: 'datetime',
		  value: new Date(timestamp3+down-1000),
		  calendar: true,
	      done: function(value, date, endDate){
	    	  start.config.max = {
	    	            year: date.year,
	    	            month: date.month - 1,
	    	            date: date.date,
	    	            hours: date.hours,
	    	            minutes: date.minutes,
