It is about representation.
If time is represented as UTC, by user in Brazil, how is somebody in
Russia going to understand when is the meeting?
Call for trouble is when there is UTC time only as that requires users
to calculate themselves the different time zone, instead, computer is
for such calculations there.
When time is specified with time zone, then user in any ther time
zone can see that in his own time zone.
In the context of Org files, that would mean that there must exist
function which would convert time zone timestamps into local time zone
for proper representation.
Only with such functions problems are gone.
Without such function to convert time zones in different time zone,
user will see time zone from Brazil and will run into difficulties.
