Hi，Outlook
Godfrey is right, you should follow the json format[1] when you parse your json
message.
You can use following code to produce a json data-time String.
```
Long time = System.currentTimeMillis();
DateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'");
Date date = new Date(time);
String jsonSchemaDate = dateFormat.format(date);
```
