Quick info

This time server is only meant for distribution of time to secondary servers. In other words, if you get your time here, you must be willing to make your time-server available to other parties. With the formalities over, here are the vital stats on the server:

 Server   : ntp.time.za.net, using ntp v4
 Location : Midrand (JHB), South Africa
 Synch    : NTP Primary (GPS receiver clock, Trimble Ace-II w/PPS), Unix
 Access   : Anybody in South Africa providing stratum-2 service
 Contact  : Tiaan van Aardt (see below)
 Notes    : Always use the DNS name

Our time server obtains its timing information from the GPS Navstar Satellite constellation which in turn obtains its time refference from the USNO Master Clock (a conglomeration of about 50 HP Ceasium beam and 9 Sigma Tau Hydrogen Maser clocks in a single vault). The GPS receiver is typically synchronised to within 100 ns (r.m.s.) of the USNO Master Clock and our time server is synchronized to within 1 盜 of the GPS receiver.
