I assume if you're displaying a time to me with no timezone specified then my system timezone is being used. If I find a system that's displaying a timezone-less time that's not my system time zone I won't be using that system much longer. But nowadays this is exceedingly rare. I am in New Zealand so I understand your perspective, I just don't think it's a major problem.
