# Kafka Connect TimezoneConverter (Debezium) SMT Usage Reference for Confluent Cloud The `TimezoneConverter` (`io.debezium.transforms.TimezoneConverter`) Single Message Transformation (SMT) converts timestamp fields in Debezium change event records to a specific timezone. Use this SMT to normalize data across multiple regions into a consistent timezone (for example, UTC). For complete details, see the official Debezium [TimezoneConverter SMT](https://debezium.io/documentation/reference/stable/transformations/timezone-converter.html) documentation. ## Limitations - The `TimezoneConverter` SMT is only available for Oracle XStream CDC Source and managed Debezium connectors on Confluent Cloud. ## Predicates Transformations can be configured with *predicates* so that the transformation is applied only to records which satisfy a condition. You can use predicates in a transformation chain and, when combined with the [Kafka Connect Filter (Kafka) SMT Usage Reference for Confluent Cloud](filter-ak.md#ak-filter), predicates can conditionally filter out specific records. For details and examples, see [Predicates](filter-ak.md#predicates).
