> *Issue*
> The following query returns the same data for the second column as the first:
> {code:sql}
> select date_add(cast('2015-01-24 07:27:05.0' as timestamp), interval '3' HOUR), date_add(cast('2015-01-24 07:27:05.0' as timestamp), interval '5' HOUR) from (values(1));
> +------------------------+------------------------+

> +------------------------+------------------------+
> {code}
> If each column is run separately, then it produces correct result:
> {code:sql}
> select date_add(cast('2015-01-24 07:27:05.0' as timestamp), interval '3' HOUR) from (values(1));
