They have a book of times and possitions, and the book is only good for a year or two... so needs to be reprinted, and on reprints, they can take care of the leap second issue... A second wrt sextants on the surface of the earth is about a quarter of a mile, and the rest of the reading is less precise than that, so even if you are a second off, you won't be that much further off course.. so, the only fix for a sextant is a new table of numbers... don't forget the tables HAVE to be updated for precisely the reason leap seconds are inserted... -- John-Mark Gurney Voice: +1 415 225 5579 "All that I will do, has been done, All that I have, has not."Received on Tue Jan 03 2006 - 22:49:22 UTC
