I agree. But the same effects can be achieved by waiting for local jurisdictions to change the existing LCT offsets as the problem becomes locally serious. They've done it many times in the past and can easily do so again. The fact that America/New_York is either five or four hours behind UTC is not carved in stone anywhere, it's just what happens to work right now. A change to being either four or three hours behind will not have nearly the same disruptive effect as a disruption in UTC. And perhaps people won't even bother. If people in Urumqi right now can tolerate a three-hour difference between LMT and LCT, a slightly different relation between the sun and the clock may seem quite tolerable to our great^20-grandchildren. (Astronomers will howl. They doubtless howled when we broke the connection between the calendar and the synodic month, too. IERS can even maintain OldUTC for their benefit; what matters is what the basis of LCT is, since we all live our lives primarily by LCT.) -- In politics, obedience and support John Cowan <[EMAIL PROTECTED]> are the same thing. --Hannah Arendt http://www.ccil.org/~cowan
