> Wrong Result 1 :
> {code}
> select l_shipdate, `month`(l_shipdate) from cp.`tpch/lineitem.parquet` where l_shipdate = date '1994-02-01' limit 2;
> +-------------+---------+
> | l_shipdate  | EXPR$1  |
> +-------------+---------+
> | 1994-02-01  | 1       |
> | 1994-02-01  | 1       |
> +-------------+---------+
> {code}
> Wrong Result 2 : 
> {code}
> select l_shipdate, `day`(l_shipdate) from cp.`tpch/lineitem.parquet` where l_shipdate = date '1998-06-02' limit 2;
> +-------------+---------+
> | l_shipdate  | EXPR$1  |
> +-------------+---------+
> | 1998-06-02  | 1       |
> | 1998-06-02  | 1       |
> +-------------+---------+
> {code}
> Correct Result :
> {code}
> select l_shipdate, `month`(l_shipdate) from cp.`tpch/lineitem.parquet` where l_shipdate = date '1998-06-02' limit 2;
> +-------------+---------+
> | l_shipdate  | EXPR$1  |
> +-------------+---------+
> | 1998-06-02  | 6       |
> | 1998-06-02  | 6       |
> +-------------+---------+
> {code}
> It looks like we are getting wrong results when the 'day' is '01'. I only tried month and day hive functions....but wouldn't be surprised if they have similar issues too.
