    var mon = (this.getMonth() + 1)+'';
    var month = mon.length==1?'0'+mon:mon;
    var da = this.getDate()+'';
    var day = da.length==1?'0'+da:da;
    var hours = this.getHours()+'';
    var hour = hours.length==1?'0'+hours:hours;
    var min = this.getMinutes()+'';
    var minutes = min.length==1?'0'+min:min;
      return this.getFullYear() + "-" + month + "-" + day+ "  " + hour + ":" + minutes;
