+#### Expressing Date / Datetime / Timezone information
+
+Given the complexity of handling various date and time formats (e.g., date, datetime, time, timestamp, timestamp with and without timezone), the existing `logicalType` options currently support only `date`. To specify additional temporal details, `logicalType` should be used in conjunction with `logicalTypeOptions.format` to define the desired format.
