A list of public NTP servers can be obtained from: http://www.eecis.udel.edu/~mills/ntp/servers.html. Please read the usage information on the page prior so using a server. Not all servers have the available bandwidth to allow a large number of systems synchronizing against them. Therefore it is a good idea to contact a system's administrator prior to using his/her server for NTP services.
