While these may be cloud-init problems in Stretch, it's kind of easy to
do this in a user metadata script.

Here, I don't see any issue at all. You'll get hardware clock as UTC,
and configure your VM with local timezone if you like. That's the normal
behavior, and I don't see any reason why you would like a different setup.

Why don't you do all of this in a user-data script?

Note that all of what I'm telling/asking here is probably what the
release team will ask if we request for a new version to get into
Stretch. If we don't have the answers, then probably we shouldn't even
attempt to ask the release team.
