Kafka Connect TimestampNowField SMT Usage Reference for Confluent Cloud
The TimestampNowField single message transform (SMT) is used to add a new field to the Kafka Connect record key or value, populating that field with the system timestamp at the moment the record is processed by the connector.
Important
Confluent only supports this SMT on Confluent Cloud. For complete details, see the official TimestampNowField SMT documentation.
