把上课时间改为每天的活动时间

我已经添加了一些脚本和样式到你的代码，不确定这将帮助你与否。

和我已经添加了脚本和jquery库

 <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>
 <script>
   $(function(){
     var date = new Date();
     var formatDate =  formatAMPM(date);      
     var times   = $('.time');
     $.each(times,function(){
        if(formatDate == ($(this).html())) {
          $(this).parent().addClass('active_time');
        }
     });
   });
   function formatAMPM(date) {
    var hours = date.getHours();
    var minutes = date.getMinutes();
    var ampm = hours >= 12 ? 'pm' : 'am';
    hours = hours % 12;
    hours = hours ? hours : 12; // the hour '0' should be '12'
    minutes = minutes < 10 ? '0'+minutes : minutes;
    var strTime = hours + ':' + minutes + ' ' + ampm;
    return strTime;
  }
 </script>
