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