 <div class="block">Retrieves embedded metadata timestamps from Kafka messages.
  If a record has a negative (invalid) timestamp, a new timestamp will be inferred from the current stream-time.
  <p>
  Embedded metadata timestamp was introduced in "KIP-32: Add timestamps to Kafka message" for the new
  0.10+ Kafka message format.
  <p>
  Here, "embedded metadata" refers to the fact that compatible Kafka producer clients automatically and
  transparently embed such timestamps into message metadata they send to Kafka, which can then be retrieved
  via this timestamp extractor.
  <p>
  If the embedded metadata timestamp represents <i>CreateTime</i> (cf. Kafka broker setting
  <code>message.timestamp.type</code> and Kafka topic setting <code>log.message.timestamp.type</code>),
  this extractor effectively provides <i>event-time</i> semantics.
  If <i>LogAppendTime</i> is used as broker/topic setting to define the embedded metadata timestamps,
  using this extractor effectively provides <i>ingestion-time</i> semantics.
  <p>
