Well, yes. But that's a matter of verbal labels. The Gregorian calendar extends to all future time: what is not known is the date on which it will be replaced in civil use by a further refinement. We know we will need one eventually, both because of the current annual discrepancy of about 27 seconds between the Gregorian and tropical years, and because of future changes in the length of the tropical year. -- John Cowan [EMAIL PROTECTED] www.reutershealth.com www.ccil.org/~cowan If a traveler were informed that such a man [as Lord John Russell] was leader of the House of Commons, he may well begin to comprehend how the Egyptians worshiped an insect. --Benjamin Disraeli
