> Here's an easy way to reproduce:
> {code}
> create table round_test(k bigint primary key);
> upsert into round_test values(1380603308885);
> select round(k/1000000,0) from round_test;
> +----------------------------------------+
> |             (K / 1000000)              |
> +----------------------------------------+
> | 1380603                                |
> +----------------------------------------+
> select round(k/1000000,0) x from round_test group by x;
> +----------------------------------------+
> |                   X                    |
> +----------------------------------------+
> | null                                   |
> +----------------------------------------+
> {code}
> Here's a work around:
> {code}
> select round(cast(k as date),'MINUTE',30) x from round_test group by x;
> +-------------------------+
> |            X            |
> +-------------------------+
> | 2013-10-01 05:00:00.000 |
> +-------------------------+
> select cast(round(cast(k as date),'MINUTE',30) as bigint) x 
> from round_test group by x;
> +------------------------------------------+
> |                    X                     |
> +------------------------------------------+
