24# Hereafter should be "server" or "peer" statements to configure
25# other hosts to exchange NTP packets with. Peers should be selected
26# in such a way that the network path to them is symmetric (that is,
27# the series of links and routers used to get to the peer is the same
28# one that the peer uses to get back. NTP assumes such symmetry
29# in its network delay calculation. NTP will apply an incorrect
30# adjustment to timestamps received from the peer if the path is not
31# symmetric. This can result in clock skew (your system clock being
32# maintained consistently wrong by a certain amount).
33# 
34# The best way to select symmetric peers is to make sure that the
35# network path to them is as short as possible (this reduces the
36# chance that there is more than one network path between you and
37# your peer). You can measure these distances with the traceroute(8)
38# program. The best place to start looking for NTP peers for your
39# system is within your own network, or at your Internet Service
40# Provider (ISP).
41#
42# Ideally, you should select at least three other systems to talk
43# NTP with, for an "what I tell you three times is true" effect.
