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. 39# 40 41#peer an.ntp.peer.goes.here 42#server an.ntp.server.goes.here 43 44# Public servers from the ntp public pool project.
