Configuring the Network Time Protocol (NTP)
Getting Started with NTP
/usr/sbin/ntpq -p ntp.adelaide.edu.au
This time server in Australia has one excellent stratum-1 source
(tictoc.tip.CSIR) which it is currently synchronized to, one stratum-1
source which hasn’t responded in a while (reach=0), and a wide selection
of stratum-2 sources (attractive candidates marked with "+"). Some of
the stratum-2 sources are less attractive due to high delay, offset, and
dispersion numbers. They are marked "falseticker" ("x" in column one).
This time server in Australia might be a good choice for you if you are
reasonably nearby, but it is probably not a good choice for time clients in
North America.
