Not likely, since 1752 was when the entire British *Empire* (not just its colonies) switched to the Gregorian system. Most of the rest of Europe had switched at various earlier times. So your "time-travel" effect wouldn't have worked between England and North America. And anyway, the same effect could be achieved with far less effort simply by crossing the English Channel from France (Gregorian) to England (Julian). ---------------------------------------------------------------------- Bob Goudreau +1 919 248 6231 Data General Corporation 62 Alexander Drive goudreau@dg-rtp.dg.com Research Triangle Park, NC 27709 ...!mcnc!rti!xyzzy!goudreau USA
