It is inserted "after" and not "at". On a normal day, the one second that follows the second beginning at 23:59:59 is the one that begins at 00:00:00 (and which begins the next day). In this case, the leap second is the one that begins at 23:59:60, and the second following that one will begin at 00:00:00. As Mike said this will be the second before 1900 eastern time on 31 December. It will just be an extra second before the tone beep on WWV starting the next minute, nothing special. These generally occur every 18 months, and reconcile atomic time to astronomic time. Sorry if this has been answered already, I get a 'digest' feed here and sometimes an behind a bit. - Bob ---[Start Commercial]--------------------- World Radio TV Handbook 2006 is out.
