# Since the HW Clock could be off by a second or
# so, our GPS might get marked as a false ticker
# if we do not set the system clock to the GPS
# first.  The current correct way to do this
# according to the ntp doc is ntpd -gq -c conffile
# which must be done before ntpd is started.
# conffile should exclude the local clock, so it is
# ignored while doing the initial sync.
# ntpd -gq apparently does not work with the GPS
# when tested with the clock more than one day off
# and no ntpd.  The gps shared memory is never polled.
#
# If there is a uBlox GPS present, the time is
# read from the GPS to initialize the system time
# before NTP is started.
