   That's a good question.  While I don't know what they actually did,
often the data is placed into a central data store in which localtime has
no meaning.    Especially when it is necessary to access the appointment
from anywhere in the world.   So for Geo's example, they'd have to store as
08:00 EST .   But now what happens when 08:00 EST changes to  08:00 EDT
after the fact?    At least it is easily correctible compared to the first
example, but such problems may not have been obvious when the datastore was
being designed.
