Interesting - I'll test it too when I install the patch. I wonder if
maybe the timezone files are read dynamically for function calls such as
those in your test, but only loaded at startup time for the processing
that is done for inserting and selecting timestamp values in tables.
Thanks

This actually turns out not to be true. I just applied the patch to a
test db without shutting down and when I ran the confirmation sql I got
the updated results:
SQL> select to_timestamp_tz('20070311 00:00:00 US/EASTERN','YYYYMMDD
HH24:MI:SS TZR') + to_dsinterval('0 08:00:00') TEST from dual;
TEST
