[jira] [Updated] (CALCITE-4554) TIMESTAMP WITH LOCAL TIME ZONE type is not supported in Snapshot and MatchRecognize validation

     [ https://issues.apache.org/jira/browse/CALCITE-4554?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Leonard Xu updated CALCITE-4554:
--------------------------------
    Description: 
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?

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 situation?
