> The query fails with exception:
> {code:java}
> Caused by: java.lang.ClassCastException: java.sql.Time cannot be cast to java.lang.Integer

>  at org.apache.calcite.linq4j.EnumerableDefaults.groupBy_(EnumerableDefaults.java:825)
>  at org.apache.calcite.linq4j.EnumerableDefaults.groupBy(EnumerableDefaults.java:764)
>  at org.apache.calcite.linq4j.DefaultEnumerable.groupBy(DefaultEnumerable.java:308)
>  at Baz.bind(Unknown Source){code}
> We also need to support type cast from *Time/TimeStamp* to *Integer/Long*
