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