  +For `TIMESTAMP` columns who's default value is specified as `CURRENT_TIMESTAMP` or `NOW`, the value _1970-01-01 00:00:00_ will be used as the default value in the Kafka Connect schema.
  +Change messages will contain the field's default value
  +(unless an explicit column value had been given), so there should rarely be the need to obtain the default value from the schema.
  +Passing the default value helps though with satisfying the compatibility rules when link:/docs/configuration/avro/[using Avro] as serialization format together with the Confluent schema registry.
