Afkak does not set creation timestamps in kafka messages

[scottmbaker]

We've noticed that our kafka messages arriving with time=-1. We were able to work around this by changing our kafka brokers' log.message.timestamp.type setting from the default of CreateTime to LogAppendTime. However, we'd prefer that kafka messages get stamped with the creation time, which we believe requires changes to the producer client.

Yes, this is a missing feature. Afkak currently produces to the broker using Message/MessageSet v0, which does not include a timestamp. We have work planned to implement Message/MessageSet v1 and Record/RecordBatch (which replace Message/MessageSet), but I don't have a timeline for it. Coordinated consumers are higher priority for us.
