Watson IoT Platform - Node-RED - 日付・時刻の追加

#日付・時刻の追加
- Node-REDのフローで日付・時刻を追加します。
- [Node-REDのフローをコピーする方法](http://qiita.com/egplnt/items/84b244a50d8bdaced324)を参照して、下記のフローをコピペします。

- フロー左端のinjectノードのボタンを押して出力を確認します。
- 「日付・時刻の追加」functionノードの内容は以下の通りです。


```js:日付・時刻の追加
var d = new Date();
var localTime = d.getTime();
var localOffset = d.getTimezoneOffset() * 60000;
var utc = localTime + localOffset;
var offset = -9.0;
var result = utc - (3600000 * offset);
var date = parseInt(new Date(result) / 1000);
var dt = new Date(result);

var year = dt.getFullYear();
var month = dt.getMonth()+1;
var day = dt.getDate();
var hour = dt.getHours();
var minute = dt.getMinutes();
var second = dt.getSeconds();
if (!msg.payload) {
    msg.payload = { "initial": "value" };
}
msg.payload.date = {
        "date": date,
        "year": year,
        "month": month,
        "day": day,
        "hour": hour,
        "minute": minute,
        "second": second
};
return msg;

```


- `msg.payload.date`もしくは`msg.payload.date.xxx`で日付・時刻の値を取得できる事を確認します。
- IoTアプリの「IBM IoT App In」ノードから「delay 5s」ノードへ接続します。

- `msg.payload.d`でセンサーからの値が取得できる事を確認します。
