It easy for one person to tell many students a single time (UTC), but it
is difficult for each student to convert that to their particular case.

It is difficult for one person to make many conversions each dedicated
to a student; but that will make it easy for each student :-)

When that person wants to make many conversions then one person would
like to make direct conversions, without going to UTC, to make the task
just a little simpler.

It is difficult for the person to imagine all the students, and their
regions, that might come to the lecture, and where they might come from.
  The solution to that would be to reduce the number of time zones, or to
simplify them.

If we had simpler time zones then we'd see a shorter unfolding menu of
times in the IETF Agenda.
