Yii2如何在FullCallendar中设置时间格式？

<?php
use yii\web\View;

$this->registerCssFile('https://cdnjs.cloudflare.com/ajax/libs/fullcalendar/3.10.2/fullcalendar.min.css', ['position' => View::POS_HEAD]);
$this->registerJsFile('https://cdnjs.cloudflare.com/ajax/libs/fullcalendar/3.10.2/fullcalendar.min.js', ['position' => View::POS_END]);
?>

<div id="calendar"></div>

$(document).ready(function() {
    $('#calendar').fullCalendar({
        header: {
            left: 'prev,next today',
            center: 'title',
            right: 'month,agendaWeek,agendaDay'
        },
        defaultView: 'month',
        timeFormat: 'HH:mm' // 设置时间格式为24小时制
    });
});
