I doubt this statement would turn out to be true (since agreements on standardized units of measurement is somewhat older than the interwebs etc) but mostly I don't see how the political mess you propose is worth the "win" of not having to deal with the odd leap-second now and then. I could think of tastier fish to fry - for instance a way to do secure time at Internet scale.
