The Network Time Protocol (NTP) is a mechanism for synchronising the time on computers. When the full NTP implementation is used, it is capable of maintaining the same time on two computers with an accuracy of around 1 ms - 30 ms despite the varying delays in internet propagation.
Further information about NTP can be obtained from the main NTP website at http://www.ntp.org/(external link)
The MSL NTP servers are synchronised using a 1 pulse per second signal to the New Zealand Time Standard. The server time is typically stable with respect to the time in the caesium clocks to around 1 microsecond, but the variability in the network delays limits the accuracy for remote clocks/clients.
The servers are publicly available to all connections from within NZ. But please note, these servers only respond to NTP and "Simple Network Time Protocol” (SNTP) requests. They do not respond to "datetime" requests.
