    }
  },
  watch: {
    value: {
      handler() {
        this.dateValue = new Date(this.value)
        this.secondIdx = this.dateValue.getSeconds()
      },
      immediate: true
    }
  },
  methods: {
    handleConfirm(val) {
      val.setSeconds(this.secondIdx)
      this.$emit('input', val.getTime())
    },
    handleChange() {
      this.secondIdx = arguments[2]
