    Description copied from class: TimestampPolicy
    
    Returns record timestamp (aka event time). This is often based on the timestamp of the Kafka record. This is invoked for each record when it is processed in the reader.

  - getWatermark
```
public org.joda.time.Instant getWatermark(TimestampPolicy.PartitionContext context)
```
    Description copied from class: TimestampPolicy
    
    Returns watermark for the partition. It is the timestamp before or at the timestamps of all future records consumed from the partition. See UnboundedSource.UnboundedReader.getWatermark() for more guidance on watermarks. E.g. if the record timestamp is 'LogAppendTime', watermark would be the timestamp of the last record since 'LogAppendTime' monotonically increases within a partition.
