The ntp.conf on the "client" should, at a minimum, consist of:
driftfile /path/to/ntp.drift
server <address/hostname of your ntp server>
Replace "/path/to/ntp.drift" with a full path + filename to a
location which is writable ny the ntp user. A typical location is
"/var/lib/ntp/ntp.drift".

This will not do what you think it will do.
If you have no real time sources (i.e. remote time servers or locally
attached ref-clocks) available you may use the Undisciplined Local
Clock (or LocalCLK or LOCAL) or Orphan Mode.
The LocalCLK and Orphan Mode merely allow ntpd to claim to synchronized
to _something_ and serve time to others. They do not make the time
correct. Nor do they control any drift or make your clock tick at the
correct rate.
If at all possible you should provide a sufficient number of real time
sources to ntpd.
If your application is not critical you may wish to use the NTP Pool
(see http://support.ntp.org/pool and http://www.pool.ntp.org/). The
mininal configuration for a server using the pool is:
driftfile /path/to/ntp.drift
I server 0.pool.ntp.org iburst
server 1.pool.ntp.org iburst
server 2.pool.ntp.org iburst
server pool.ntp.org
To use the just Undisciplined Local Clock the minimal configuration is:
driftfile /path/to/ntp.drift
server 127.127.1.0
fudge 127.127.1.0 stratum 10
To use just Orphan Mode the minimal configuration is:
driftfile /path/to/ntp.drift
tos orphan 10
You may add the 127.127.1.x lines or the orphan line to an ntp.conf
in addition to remote time servers. Orphan Mode is preferred if your
version of NTP supports it.
