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. -# -server 127.127.1.0 # local clock -fudge 127.127.1.0 stratum 0 - -# -# PPS Clock. This driver is used to capture a 1-pps signal when the PPS -# kernel modifications are not in use. It can be configured for the -# tty_clk or ppsclock streams module or no module at all, assuming the -# RS232 connector is properly wired. Normally, the 1-pps signal is -# generated by a radio clock, in this cast the Spectracom clock -# 127.127.4.1 also configured for this host. When used this way, the -# associated radio clock normally has the prefer keyword in the serve -# command line. The PPS driver then will be selected only if the prefer -# peer is operating within nominal error bounds.
