I've gotten in the habit of giving times in UTC explicitly when talking to people in other timezones. Even if I give a time in another specific timezone. (All of my computers get a world clock with a few locations and UTC)

A friend of mine works in a company with employees all over the world for 24hr coverage with handoff meetings where shifts overlap, seeing them do it for call times sold me on the idea.

It's still possible for the world to adopt something like Swatch Internet Time for coordinating across timezones/"without" timezones. Possible, but probably unlikely.
