How bootstrap-datetimepicker displays only dates

recently encountered such a problem when using bootstrap datatimepicker

/ / instantiate time control and configure Chinese display

        $(".form_datetime").datetimepicker({
            viewSelect: "month", // 
            language: "zh-CN",
            todayBtn: true,
            autoclose: true
        });

Why is it set in this way, and the interface can still display the option of hours?
