Nice article. There's also been a lot of discussion about the leap second, not too surprisingly, on the leap seconds list <http://www.mail-archive.com/leapsecs@rom.usno.navy.mil/>. Here's a brief summary. Several people will be observing clocks when the leap second occurs and plan to publish what they observe. Tom Van Baak is perhaps the best-known at this; see his "How to Watch a Leap Second" <http://www.leapsecond.com/notes/leap-watch.htm> and his Leap Second Countdown Clock <http://www.leapsecond.com/java/nixie.htm>. Last week the GPS Operations Center of the US Air Force Space Command's Space Analysis Center published an advisory <http://www.schriever.af.mil/GpsSupportCenter/archive/advisory/Leap_Second_Ev...> that talks about the potential problems in civilian and military uses of GPS near the leap-second occurrence. Since this week's is the first leap second since 1998, a lot of hardware and software will be tested in the field for the first time. For people that have gear that need subsecond timing, GPS Operations Center suggests that you review your leap second support, contact your supplier as needed, and monitor your system through the leap second event. They give contact addresses for US military and civilian users (the Coast Guard and the FAA, for the latter).
