How does that account for out of order records?

What about kstream-kstream joins?  The output from the join could be
triggered by a record received from either stream depending on the order
they are received and processed.  If the timestamp of the output is just
the timestamp of the latest received record, then it seems that the
timestamp could be that of either record.  Although I suppose that the best
effort stream synchronization effort that Kafka Streams attempts means that
usually the timestamp will be that of the later record.
