> At the moment the timestamp extractor is configured via a StreamConfig value to KafkaStreams.  That means you can only have a single timestamp extractor per app, even though you may be joining multiple streams/tables that require different timestamp extraction methods.
> You should be able to specify a timestamp extractor via KStreamBuilder.stream/table, just like you can specify key and value serdes that override the StreamConfig defaults.
