I think the closest thing to what you're trying to do is:

slo=> set timezone  =  'GMT';
SET
slo=>  select '2001-01-01'::date::timestamptz at time zone 'EST' ;
      timezone       
---------------------
 2000-12-31 19:00:00
(1 row)


Why are you not just storing a "timestamp with timezone" with the actual time
of the event, and a second column with the local time zone in which you can
choose to use to display the time?
