> The current {{case class Message(msg: Any, timeInMillis: TimeStamp)}} is not extensible with an additional timestamp field while users' message may already carry that information.  I don't think we care about what is stored in the message but what we can get from it. 
> I propose to add a new interface {{Message}} with {{value}} and {{timestamp}} fields/methods and rename the current {{Message}} to {{DefaultMessage}} as a default implementation.
