The NIST has not yet updated its official leap-seconds.list, but here
comes one that can be used in the meantime. It lists the December 2008
leap, and is authoritative until just before the next open date at the
end of June 2009.

For ntp-stable releases: place the leap-seconds.3424118400 file into
<keysdir>, and create an "ntpkey_leap" symlink to it. You must have
a minimal autokey setup: A <keysdir>, host cert and key, and at least
one "crypto" command in ntp.conf

For ntp-dev: place the leap-seconds.3424118400 file into /etc, and
create an "ntp.leap" symlink to it.


With this file and ntp-stable, you are guaranteed to leap in time. With
ntp-dev, you are additionally guaranteed to ignore any other leap
announcement from external sources until 28 June 2009. Because of course
such other announcement can only be wrong.


Serge.
