GMT timezone - login trigger

Looking for some advice regarding timezones.  On my HP-UX servers, I have 
serveral databases running (v8-v10).  I want one of those databases to run at 
GMT time - for storing sysdate, etc,  
The TZ=EST5EDT at the server level.  
The database is already setup for GMT time, verified by the following:
select dbtimezone from dual 
DBTIMEZONE 
---------- 
GMT 
According to the notes on Metalink, the above only applies to columns defined 
as "timestamp with timezone". 
A check of the date shows the server time being used (select sydate from dual). 
It looks like my only option is a login trigger does an "alter session set 
time_zone=dbtimezone;"   
Any other ideas?   The database in question for this is a 9.2.x
Thanks.
