Bootstrap-datetimepicker the timeline arrows cannot be displayed

***************************************************

I use Bootstrap-datetimepicker+bootstrap v3, but this plugin uses the time, and does not match V3, still call is bootstrap V2 icon, the code is:

<i class= "Icon-arrow-right" ></i>

Workaround:

The class value of input uses Form-control or the Bootcssver value is set directly to 3 in the DateTimePicker options, otherwise DateTimePicker will not show arrows

Bootcssver:3,

eg

<input id= "Dtstart" name= "Dtstart" type= "text" style= "width:130px" ></input>

        $ ("#dtStart"). DateTimePicker ({  minview: "Day",
            bootcssver:3,
            format: "Yyyy-mm-dd hh:00",//Date format
            autoclose:true,//Check close
            todaybtn:true//today button
        });
		
		
		$ ("#dtEnd"). DateTimePicker ({  minview: "Month",//settings only displayed to the month
            bootcssver:3,
            format: "YYYY-MM-DD",//Date format
            autoclose:true,//Check Close
            todaybtn:true//today button
        });
		
        $ ("#timeEnd"). DateTimePicker ({  
            bootcssver:3,
            format: "HH",//Date format
            startview:1,
            minutestep:60 ,
            Minview: "Day",
            autoclose:true,//check close
            todaybtn:true//today button
       });
