小程序 苹果IOS 时间格式化的问题？nan/nan/nan/nannan:nan

在写小程序的时间格式化时，出现了渲染 nan/nan/nan/nannan:nan 的BUG，
找了很长时间，没有找到原因，查阅了官方帮助文档。
也有百度上查找问题，报错的写法是这样如下：

 onLoad: function (options) {
    var time = new Date(2017, 6, 14, 10, 40, 0, 0);
 
    this.setData({
      time: time
    })
  },

=================================================================
而最终找到原因，对于time 要进行toLocaleDateString()处理。
 onLoad: function (options) {
    var times = new Date(2017, 6, 14, 10, 40, 0, 0);
    var time = times.toLocaleDateString();

    this.setData({
      time: time
    })
  },

demo.js

Page({

  /**
   * 页面的初始数据
   */
  data: {
    day: 5
  },

  /**
   * 生命周期函数--监听页面加载
   */
  onLoad: function (options) {
    var times = new Date(2017, 6, 14, 10, 40, 0, 0);
    var time = times.toLocaleDateString();

    this.setData({
      time: time
    })
  },

  /**
   * 生命周期函数--监听页面初次渲染完成
   */
  onReady: function () {
    
  },

  /**
   * 生命周期函数--监听页面显示
   */
  onShow: function () {
    
  },

  /**
   * 生命周期函数--监听页面隐藏
   */
  onHide: function () {
    
  },

  /**
   * 生命周期函数--监听页面卸载
   */
  onUnload: function () {
    
  },

  /**
   * 页面相关事件处理函数--监听用户下拉动作
   */
  onPullDownRefresh: function () {
    
  },

  /**
   * 页面上拉触底事件的处理函数
   */
  onReachBottom: function () {
    
  },
