So i did it like this:

$('.my-btn-class').click(function(e) {  
            $(".time-class").attr('value', '09:00:00')
            $( '.time-class' ).pDatepicker( {
                onlyTimePicker: true,
                format: 'HH:mm',
                timePicker: {
                    second: {
                        enabled: false
                    }
                },
                autoClose: true,
                onSelect: function (unix) {

                },
            });
        });
