Ok. A 10:00 o'clock appointment that was set up before DST to hit after
DST is now a 9:00 o'clock appointment.

Afer I got all of our servers updated to the new time/timezone info, all
of our workstations were an hour ahead. They were putting a DST shift
on top of the DST shift they were receiving from the server, so on our
XP worksdtations, we are not adjusting for DST. In case it matters.

Bottom line is all of our appointments were adjusted. How do I fix them?
