I recall learning in school (a long time ago) that the the correct terminology for noon is actually 12:00 m., but nobody seems to use that. It would make sense for the U.S. to adopt a 24-hour clock like the rest of the world, but the metric system also makes sense and we seem to do our best to avoid that also (I haven't heard the "metrify or petrify" argument in quite a while.) 73, Bob, N7XY Bainbridge Island, WA ---- Via the amsat-bb mailing list at AMSAT.ORG courtesy of AMSAT-NA.
