This is crazy. It looks like a new session gets the new information.
I connect to the database with the old files in place in the zoneinfo
directory. I ran the script and the results were wrong.
I loaded the new files without disconnecting from sqlplus and ran the
script again. The results were wrong.
I restarted sqlplus and ran the script and the results were correct.
It looks like a new database session reads the zoneinfo files?
Another great testing job from Oracle support. At least they are
consistent.

Yes, I did notice the same thing. Without restarting the instance, I
was able to see the updated results.
Thanks

That would be great to no have to restart each database.
Anyone else do this and found that a restart is not necessary?

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
