# Kafka Connect TimezoneConverter (Debezium) SMT Usage Reference for Confluent Platform The `TimezoneConverter` SMT (`io.debezium.transforms.TimezoneConverter`) 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 such as UTC. For complete details, see the official Debezium [TimezoneConverter SMT](https://debezium.io/documentation/reference/stable/transformations/timezone-converter.html) documentation. To convert the format of a timestamp field, see [Kafka Connect TimestampConverter SMT Usage Reference for Confluent Platform](timestampconverter.md#timestampconverter). ## Limitations The `TimezoneConverter` SMT is only available for Oracle XStream change data capture (CDC) Source and managed Debezium connectors on Confluent Platform. ## Predicates Configure transformations with predicates to ensure they process only records that satisfy a particular condition. You can also use predicates in a transformation chain with the [Kafka Connect Filter (Kafka) SMT Usage Reference for Confluent Platform](filter-ak.md#ak-filter) to conditionally filter specific records. For more information, see [Predicates](filter-ak.md#predicates).
