Change Format Time AM / PM to 24 hour Timeline Day fullcalendar

Question

I have a project user jQuery fullcalendar-scheduler, I want to format time to use 24 hour. I have config as below, but it didn't work. Is there something wrong with my code ??

{
        now: moment().format('YYYY-MM-DD'),
        contentHeight: setUpHeight(),
        aspectRatio: 1.8,
        header: {
            left: 'today prev,next',
            center: 'title',
            right: 'timelineDay,timelineMonth'
        },
        timeFormat: 'H(:mm)',
        defaultView: 'timelineDay',
        resourceLabelText: 'Devices',
        resources: resources,
        events: schedules,
        eventRender: function (event, el) {
            el.qtip({
                content: {
                    delay: 1e3,
                    text: function () {
                        return $('#qtip-content-custom').html(event.description);
                    },
                },
                style: { classes: 'qtip__clases' },
                position: {
                    target: 'mouse',
                    adjust: { x: 7, y: 5 }
                },
            });
        }
}

And the result still use AM / PM, like this :
