If that's working for you, you might just want to leave it alone;
but just so you know:
 
If you declare the column as TIMESTAMP WITH TIME ZONE, that it
stores the timestamp as UTC regardless of what your server's
definition of time zone is.  (It doesn't actually store the time
zone -- it just normalizes the time into UTC for storage.)  On
retrieval it shows that UTC moment in the local timezone.  So, all
that work you're doing to switch the time zone info around would be
pretty automatic if you used the other type.
