 1 function get_next_day(str_date){
 2         var d="";
 3         d=new Date(str_date);
 4         d.setDate(d.getDate()+1);
 5         var y=d.getFullYear();
 6         var m=d.getMonth()+1;
 7         var dd=d.getDate() < 10?'0'+parseInt(d.getDate()):parseInt(d.getDate());
 8         return y+"-"+m+"-"+dd;
 9 }

12 function count_days(date_in,date_out){
13         
14         var tmp_datein     = date_in.replace(/:/g,'-');
15             tmp_datein     = tmp_datein.replace(/ /g,'-');
16         var tmp_dateout = date_out.replace(/:/g,'-');
17             tmp_dateout = tmp_dateout.replace(/ /g,'-');
18         var date_time1    = tmp_datein.split('-');
19         var date_time2     = tmp_dateout.split('-');
20         
21         var timestamp1    = new Date(Date.UTC(date_time1[0],date_time1[1]-1,date_time1[2]));
22         var    unix_time1 = parseInt(timestamp1.getTime()/1000);
23
