My TO_CHAR function is now an hour off thanks to Daylight Savings Time.
The dates are correct (I'm in EST: TZ=-04) but my function now returns TIME

You are leaving out something critical. Based on what you've shown us,
you shouldn't get either answer, you should get "03/17/2011 06:21 PM".
select to_char(timestamptz '2011-03-17 18:21:50-04', 'mm/dd/yyyy hh:mi AM');
to_char

My money is on an accidental conversion between timestamp and
timestamptz in some part of the function you haven't shown us.
Cheers,
Steve
