> Now we still use java.sql.Timestamp to be default conversion class for 
> TimestampType.
> We should use design of new Type System to use java.time.Local***.
> NOTE, This may affect user behaviour:
> eg: UDF with eval(Object o), now will pass a java.time.Local*** instead of 
> java.sql.**.
> Compatibility method: use DataType.bridgedTo(java.sql.**.class);
