My challenge is that sometimes I don't know what time zone I will be
in at the time I make an appointment. For example, if I make an
appointment for a phone conference call in two weeks at 2pm while I
am in Salt Lake City. Then I have to go to NY duing the time I have
the call scheduled. Well, Outlook changed the time to 4pm but the
call is really for 2pm. Is there a way to "freeze" the time zones for
appointments?

Outlook did NOT change the time, you did. Outlook always uses GMT
internally. When you change your time zone, Outlook displays the same GMT
time as represented in that zone. You don't want Outlook to freeze the time
zone, you want it to float the appointments. Have you looked at the
alternate time zone feature of Outlook?
