The model described in the specification RFC-1305 is based on a phase-lock loop (PLL) design, which is optimum or near optimum for the update intervals used for NTP peers and radio clocks. The network packets normally exchanged between NTP clients and servers to synchronize time don't contain any secrets, just the current time. NTP users are strongly urged to take immediate action to ensure that their NTP daemons are not susceptible to being used in distributed denial-of-service (DDoS) attacks. The telescope can point to within arc seconds of a star and that implies that the computer clock needs to be within 50 ms.

Under Windows 7, however, the clock can be anything up to 0. org servers as a reference source this has worked very well under XP for several years and the clock was seldom more than a few milliseconds out. NTP dynamically selects the optimal poll interval between the values of minpoll and maxpoll, which default to 64 and 1024 seconds respectively and are correct for most environments. NTP communication then uses unicast associations, as if the discovered NTP servers were listed in ntp. NTP users are strongly urged to take immediate action to ensure that their NTP daemons are not susceptible to being used in distributed denial-of-service (DDoS) attacks. org names point to a random set of servers that will change every hour. config file on the playback machines that does this is server 10.
