However, time offsets are not very interesting. Org is (also) about
appointments, deadlines... so timezones are more accurate.

Also, Emacs contains "timezone.el", which, I assume, should take care of
all the heavy duty concerning these beasts, as far as an API is
concerned.

This requires care, but it should be doable, really, don't you think?

Thank you for the reference. I didn't know about it.
