If your ntpd is relying upon other NTP servers (that is, is stratum 2
or higher), it will not announce the pending leap second starting
exactly at midnight UTC in a few minutes, but should within a few
polling intervals. With the default maximum interval of 1024 seconds
being about 17 minutes, by 00:34 30-June UTC most systems should have
picked it up that will.

If it helps at all, I have a small Windows program called NTPLeapTrace. It
displays the upstream leap indications contributing to a target ntpd's leap
election. Although the same can be done using a series of ntpq queries,
it's easier to enter a server or client name and click. Download here:

I've just added a second screen-shot show the expected output under "Leap
Second Today" conditions. I hope the program will be of some help.
Cheers,
David
