   The following figure shows the components related to processing timestamps:

   From a usage perspective, the behavior of `Spark Gravitino Connector` should 
be consistent with `Spark Hive Connector`; there should exist a type in 
Gravitino that has the same semantics as the `timestamp` type in HMS because 
Hive only supports `timestamp without timezone` (see details at[ the 
doc](https://hive.apache.org/docs/latest/languagemanual-types_27838462/#timestamps)),
 so the `timestamp without time zone` type in Gravitino should correspond to 
the `timestamp` type in HMS. When users attempt to use `timestamp with time 
zone` through Gravitino in the Hive catalog, an exception should be thrown.
