[Json-rpc-java] handling Date

[Michael Clark]

Hi Boris,

Yes you are right. Date support is pretty limited. Your best workaround 
for the moment is to do something like the following to make sure you 
send a number.

JSONObject["time"] ? JSONObject["time"] : 0

You could also write a custom serializer to handle your string format.

Unfortunately as the de-serialization on the JS side doesn't support 
constructors for the Date class (it can't be represented in simple 
JSON), you will receive a number in milliseconds (or a String if you 
wrote a custom serializer).

To unmarshall the date on the JS side you need to do:

var date = new Date(result.time);

Michael.
