FullCalendar在添加到月视图时更改事件的开始/结束时间

在select上添加新事件时,FullCalendar似乎正在更改我的事件的开始和结束时间。这仅在月视图中发生,而不在agendaWeek视图中发生。

mounted () {
  let vm = this
  $(this.$refs.calendar).fullCalendar({
    defaultView: 'month',
    header: {
      left: 'title',
      center: '',
      right: 'today agendaWeek,month prev,next'
    },
    allDaySlot: false,
    allDayDefault: false,
    firstDay: 1,
    select: function (start, end, jsEvent, view, resourceObj) {
      vm.addEvent(start, end, view)
    }
  })
},
methods: {
  addEvent: function (start, end) {
    // Here this.hour and this.minute are variables which in my example would be 6 and 0
    from = moment(start).set({'hour': this.hour, 'minute': this.minute})
    to = moment(end).set({'hour': this.hour, 'minute': this.minute})
    this.renderEvent(from, to)
  },
  renderEvent: function (start, end) {
    // Make temporary id
    let tmpId = `tmp-${this.getLocalEvtId()}`

    console.log(start.format('YYYY-MM-DD HH:mm'))

    // Add new event
    $(this.$refs.calendar).fullCalendar('renderEvent', {
      id: tmpId,
      title: 'NA',
      start: start,
      end: end,
      color: '#bd362f',
      editable: false
    }, false)

    // Find newly created event
    let event = $(this.$refs.calendar).fullCalendar('clientEvents', tmpId)[0]

    console.log(event.start.format('YYYY-MM-DD HH:mm'))
  }
}

使用此代码添加事件时,第一个控制台。日志记录2018-04-10 06:00(或我设置为开始的任何时间),但第二个2018-04-10 00:00。从agendaWeek视图添加事件时,两个日志都记录在2018-04-10 06:00。有人经历过类似的问题吗?
