[~rkins] I tested these functions with hive plugin and they worked properly.
But I see that you used the classpath plugin.
Could hive's functions work with any other plugin than hive? I tested hive's
functions from drill unit tests framework and they don't work with cp plugin
there.
But drillbit can run these functions with cp plugin. Anyway they returned
correct result.

0: jdbc:drill:zk=local> select l_shipdate, `month`(l_shipdate),
DATE_PART('month', l_shipdate) from hive.`tpch/lineitem.parquet` where
l_shipdate = date '1994-02-01' limit 2;

Which version of drill did you use? I tested these functions on the last drill
master (1.10.0-SNAPSHOT) and on the 1.9.0 and got the same results.
What are the settings of your cp plugin? Is this issue still reproduced on your
environment?

> 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.
