Tanner Clary created CALCITE-5484:
-------------------------------------

             Summary: Implement BigQuery DATETIME_SUB
                 Key: CALCITE-5484
                 URL: https://issues.apache.org/jira/browse/CALCITE-5484
             Project: Calcite
          Issue Type: Sub-task
            Reporter: Tanner Clary


BigQuery's {{DATETIME_SUB(timestamp, interval)}} returns the timestamp that occurs {{interval}} before {{timestamp}}.

Example: {{DATETIME_SUB(TIMESTAMP '2008-12-25 15:30:00', INTERVAL 5 MINUTE)}} would return: '2008-12-25 15:25:00'.
