Here we go!

Yeah, I'm not convinced it's worthwhile. It's really only the one
use-case, though it would be handy.

Out of curiosity, what's your stance on supporting time zones in Org's
timestamps? It would be an enormous amount of work, obviously, but in
principle?

That's pretty much what it was before I messed with it, and I was a
little confused because no callers of `org-icalendar-convert-timestamp'
ever used the optional fourth argument at all. My thinking was that
users might want to explicitly set the timezone to "UTC". To be honest
I'm not sure why they would, but I also don't know why we'd accept t
when nothing uses it. I found the whole handling of utc-or-not a bit
confusing. What do you think?

Thanks,
Eric
