I disagree. If I make an appointment for a meeting I'm flying to, 5 timezones away, it's better to be able to say 'let's meet at 9am' rather than having to look up what time '2 hours after getting out of bed' is in that particular location. Similarly, if I read news about Japan that says 'an explosion occurred at 10pm' I prefer to know that that means 'after the regular working day' instead of having to look up when the working day ends there.
Maybe the ideal solution would involve specifying all times in two timezones (local and GMT), side-by-side? Practically, I'm now interested in adding something like a <time> HTML tag that would let users decide how they want to see it, and see it in their own localtime automatically. JQuery plugin anyone?
