what's the output of "ntpq -c rv"?
If you have a *current* leap second file, and you have configured ntpd
correctly to use it, the output should contain something like:
If these terms are missing then the leap second file has not been
evaluated by ntpd. If "leapsec=" and "expire=" report older dates then
the leap second file is outdated and ntpd has not been aware of last
recent leap second.
Please note that, if the latter is the case, ntpd 4.2.6 will not even
accept a leap second warning from its upstream servers. :-(
Anyway, it should have stepped the time a few minutes after the leap
seconds, if the upstream servers have inserted the leap second properly.
