问题：Fullcalendar 将 24 日显示为午夜，而不是 00:00

Question

由于某种原因，Fullcalendar 将午夜之后开始的事件显示为“24:15”。我们希望它显示“00:15”。我认为这是一个新问题，因为我们已经有一年的日历了，这是我第一次听说它。但我找不到任何有关如何解决它的信息。

我们使用的是 fullcalendar v4.2.0。原始代码不是我写的，但我对它相当熟悉。我们使用 REST API 获取事件，并且使用 ServiceNow。当使用 12 小时格式（am/pm）时，它显示 12a15。我尝试更改 eventTimeFormat，但没有成功。这是客户端脚本的一部分：

    /* Calendar */
c.funcs.loadCalendar = function() {
    var calendarEl = document.getElementById('calendar');
    c.calendar = new FullCalendar.Calendar(calendarEl, {
        contentHeight: 'auto',
        plugins: [ 'dayGrid','timeGrid', 'list'],
        header: {
            left: 'prev next today',
            center: 'title',
            right: 'dayGridMonth,timeGridWeek,timeGridDay,listWeek,listMonth'
        },
        buttonText: {
            dayGridMonth: 'Month',
            timeGridWeek: 'Week',
            timeGridDay: 'Day',
            listWeek: 'List Week',
            listMonth: 'List Month',
            today: 'Today'
        },
        editable: false,
        eventTimeFormat: {
            hour: '2-digit',
            minute: '2-digit',
            hour12: false
        },
        eventOverlap: false,
        firstDay: 1,
        weekNumbers: true,
        // Scripted REST API which sends Start and End date-time of current view as parameters and gets current events. 
        //events: '/api/tnas/fullcalendar_fetch_data',

        events: function(info, successCallback, failureCallback) {
            $http({
                method: 'GET',
                url: '/api/tnas/fullcalendar_fetch_data',
                headers: {
                    'X-UserToken': window.g_ck // Authorization
                },
                params: {
                    systems: c.vars.selectedSystems.map(function(system) { return system.value; }).toString(),
                    excludedTypes: c.vars.types.filter(function(type) {return !type.checked}).map(function(type) { if(!type.checked) return type.type   }).toString(),
                    start: info.start,
                    end: info.end
                }
            }).success(function(data, status) {
                successCallback(data.result.events);
            }).error(function(data, status) {failureCallback(data)});
        },
        loading: function(isLoading) {
            c.vars.calendarIsLoading = isLoading;
            $scope.$evalAsync();
        },
        // When event is rendered and put into the DOM, add a tippy.js tooltip to that element.
        eventRender: function(info) {
            tippy(info.el, {
                theme: 'light-border',
                content: info.event.extendedProps.tooltipContent,
                arrow: true,
                animation: 'fade',
                flip: false,
                boundary: 'window'
            });
        },
        eventClick: function(info){
            info.jsEvent.preventDefault();
            var p = $scope.data.page_id || 'form';
            var url = '/sp?id=' + p + '&table=' + info.event.extendedProps.table + '&sys_id=' + info.event.id + '&view=sp';
            window.open(url, "_blank");
        },
        navLinks: true,
        navLinkDayClick: function(date, jsEvent) {
            //c.calendar.gotoDate(date);
            c.calendar.changeView('timeGridDay', date);
        }
    });

    c.calendar.render();
}
/* Calendar End */

希望有人以前经历过同样的问题。任何帮助是极大的赞赏！

已修复：将 eventTimeFormat 中的 hour12 属性替换为 hourCycle: 'h23' 就可以了！

    eventTimeFormat: {
        hour: '2-digit',
        minute: '2-digit',
        hourCycle: 'h23'
    },
