I looked at a bunch, and I couldn't find any sites that asked for a date only
(no time) and yet used the 24-hour period corresponding to the user's
submission time zone, and not the date irrespective of time zone. Could you
provide a URL to one explicitly that I could look at?

I understand that the date has meaning. I just don't think sites are doing what
you think they're doing. I think the use case for a date control doesn't need a
time zone in practice.

For example, Google Calendar uses a date control only for events that are
time-zone agnostic — if I set an event to be on Thursday October 22nd 2009
while my time zone is UTC+12, and then change my time zone to UTC-12, the event
still claims to be on Thursday, even though there are no minutes in common for
those two events.

For timezone-dependent events, sites have date+time controls, which is
type=datetime.
