# Undisciplined Local Clock. This is a fake driver intended
for backup
# and when no outside source of synchronized time is
available. The
# default stratum is usually 3, but in this case we elect to
use stratum
# 0. Since the server line does not have the prefer keyword,
this driver
# is never used for synchronization, unless no other other
# synchronization source is available. In case the local
host is
# controlled by some external source, such as an external
oscillator or
# another protocol, the prefer keyword would cause the local
host to
# disregard all other synchronization sources, unless the
kernel
# modifications are in use and declare an unsynchronized
condition.
