> When I plan to support *TIMESTAMP WITH LOCAL TIME ZONE*  type in Flink project , I found  only *TIMESTAMP* is supported in system period type of *Snapshot* node and   first orderBy column type of *MatchRecognize* node in Calcite.  So I have to override the class  _org.apache.calcite.sql.validate.SqlValidatorImpl_ to skip the validate logic. 
> Both *TIMESTAMP* and *TIMESTAMP WITH LOCAL TIME ZONE* belong to *SqlTypeFamily.TIMESTAMP*, Could we also support *TIMESTAMP WITH LOCAL TIME ZONE* in these situations?
