             Summary: Add TIME/TIMESTAMP/DATE datatype handling to RexImplicationChecker
                 Key: CALCITE-1829
                 URL: https://issues.apache.org/jira/browse/CALCITE-1829
             Project: Calcite
          Issue Type: Bug
            Reporter: MinJi Kim
            Assignee: Julian Hyde


In RexImplicationChecker, we support a lot of operators and types, but it looks like time/timestamp/date datatypes are not supported.  In RexImplicationCheckerTest, there are tests for each of the aforementioned datatypes, but are disabled.

Running these ignored tests, I get the following error messages.
