A military repositioning of the GPS sats for their own purposes, perhaps? Or adjustment of the time being broadcast? I know that a coworker of mine experienced this with a GPS-based tracking system. The boat he was tracking moved from the middle of the atlantic, to the middle of europe, then eventually back the middle of the atlantic. (this was around the time of Desert Storm) Or, of course, a more general failure of the GPS time system, for whatever reason. ...david --- david raistrick drais () atlasta net http://www.expita.com/nomime.html
