> Extracting date field from timestamp should work in ANSI mode
> -------------------------------------------------------------

> Add a new ANSI type coercion rule: when getting a date field from a
> Timestamp column, cast the column as Date type.
> This is Spark's hack to make the implementation simple. In the default type
> coercion rules, the implicit cast rule does the work. However, The ANSI
> implicit cast rule doesn't allow converting Timestamp type as Date type, so
> we need to have this additional rule
> to make sure the date field extraction from Timestamp columns works.
