Please see http://doc.ntp.org/4.2.4/ntpd.html#poll for the discussion of
Poll Interval Control pertaining to NTP 4.2.4
You may also wish to review the Poll Rate Control section of
http://www.cis.udel.edu/~mills/ntp/html/rate.html (please note that all
documentation found in this tree applies to the current NTP development
You will also find the documentation for your release of NTP in the
./html directory of the appropriate source tarball.

When time sources become unreachable ntpd will continue to discipline
the clock using the currently calculated frequency correction value.
If that ntpd is configured with Orphan Mode, or with the Undisciplined
Local Clock, it will be able to continue serving time to others.
