------------------------------------

             Summary: DATE_TRUNC compile-time evaluation produces wrong results
                 Key: CALCITE-5761
                 URL: https://issues.apache.org/jira/browse/CALCITE-5761

          Issue Type: Bug
          Components: core
    Affects Versions: 1.34.0

Adding the following 3 tests to SqlOperatorTest.testDateTrunc produces assertion failures.

f.checkScalar("date_trunc(date '2015-02-19', decade)",
        "2010-01-01", "DATE NOT NULL");
    f.checkScalar("date_trunc(date '2015-02-19', century)",
        "2001-01-01", "DATE NOT NULL");
    f.checkScalar("date_trunc(date '2015-02-19', millennium)",
        "1001-01-01", "DATE NOT NULL");

Results produced:
