The standard /etc/rc.d/ntpd startup script has the "nojail" KEYWORD in it.  This means (according to the rc man page) it will be skipped when determining the rcorder of startup (i.e., it will not be executed when starting up in a jail).

If you want ntpd to start up in a jail you could put a copy of /etc/rc.d/ntpd in /usr/local/etc/rc.d and edit it to remove the "nojail" keyword.  You may have to do something similar to its dependencies based upon how the nature of the jail setup.

Cheers,

Paul.
