EDIT: I see, you were providing an example of a smart person, not an example of a smart argument. I'll let my rant stand anyway. :-)
No, it's an idiotic argument, because it essentially boils down to forcing the billions of people who do not live in the GMT timezone to adjust their mental model of "what time is office hours", and you STILL haven't solved the original problem of answering the question "Hey, you are in a different timezone, is this a good time to schedule a meeting?" You STILL need to do a lookup!
