That the article mentions airlines using UTC is a good insight. When there is a need to coordinate amongst international actors, then the importance of a globally shared time system can be agreed. But that's complete overkill for making plans to meet your friends for dinner, because a local frame of reference is the only time that is going to have meaning between you. I think the way it works now is pretty decent. Most globally coordinated systems already use UTC. You're already using it to store your database records, aren't you? If rogue states decide to monkey around with their clocks, well I don't know. Half joking, but maybe we should just turn up to those meetings late?
