             Summary: EXTRACT function doesn't work because of NULL returned from druidQuery.getConnectionConfig().timeZone()
                 Key: CALCITE-2782
                 URL: https://issues.apache.org/jira/browse/CALCITE-2782
             Project: Calcite
          Issue Type: Bug
          Components: druid
    Affects Versions: 1.18.0
            Reporter: Justin Szeluga
            Assignee: Julian Hyde


The default value for BuiltInConnectionProperty.TIME_ZONE is null. If the timezone is not set in the properties then the null is returned and a NullPointerException is thrown when PeriodGranularity initializes.

In tests, org.apache.calcite.test.CalciteAssert#assertQuery sets the timezone to UTC hiding the problem. When I issue queries from DBeaver it fails because of the NPE
