In Kafka 2.1.0 we deprecated couple of methods (
KAFKA-7277) to pass in timestamps via IQ API via Duration/Instance parameters instead of plain longs.
In Kafka 2.3.0 we introduced TimestampedXxxStores (
KAFKA-3522) and allow IQ to return the stored timestamp.
However, we never update our JavaDocs that contain code snippets to illustrate how a local store can be queries. For example `KGroupedStream#count(Materialized)` (https://github.com/apache/kafka/blob/trunk/streams/src/main/java/org/apache/kafka/streams/kstream/KGroupedStream.java#L116-L122):
We should update all JavaDocs to use `TimestampedXxxStore` and the new Duration/Instance methods in all those code snippets.
