nls_date_format question

Does anyone know why I cannot see the full date output once I issue the command:

alter session set nls_date_format = 'DD-MON-YYYY';

It appears that this works; the column is restricted to the standard a9 width. The kicker is
that this works from a few clients, but not all.

Thanks,
