If you have nothing better to do around midnight UTC tonight, then
install

and run it with
./timelog -w2005-12-31T23:59:00 -d180 >/tmp/leapsecond.log
to record the last minute of this year and the first to of the next on
any potentially interesting NTP machine that you can get hold of.
This records the BSD API, the POSIX API, and on Pentium CPUs also the
Pentium timestamp counter. Command-line options allow you specify start
time and duration of the recording.
This is meant to be portable POSIX code, but has only been tested under
Linux so far.
