The exact poll timing is irrelevant as far as NTP is concerned. The Unicast (i.e. client/server) polling scheme time-stamps the packet when it is sent from the "client", at the "server", and again when it arrives back at the "client". These three time stamps are collected at each poll interval from each time source. The NTP algorithms use these time-stamps to, over time, determine what the correct time is. -- Steve Kostecke <[EMAIL PROTECTED]> NTP Public Services Project - http://support.ntp.org/ _______________________________________________ questions mailing list questions@lists.ntp.org https://lists.ntp.org/mailman/listinfo/questions
