Thanks for the neat toy.

I didn't appreciate what was going on until I tried to graph the results.

A NetBSD box stalled the clock for a second starting at 00:00:00.5
Two Linux boxes set the clock back 1 second at 23:59:60
  (One 2.4 kernel, one 2.6.)
  One got a line of printout in 00:00 before the clock was set back.

I also got data from 2 NMEA GPS clocks.
  A Garmin 18-LVC transmitted a duplicate second at 00:00:00
    (This matched the documentation.)
  A GPSClock 200 had a duplicate second at 23:59:51.  ??
