A Natural NTP Server?
There are chronologists all over the world working constantly to find new ways of telling time that are the most accurate that can possibly be created. The first atomic clocks were developed in the 1950's and thus began the race for millisecond accuracy. ...
Using GPS For NTP Server Time Synchronisation
The GPS system is a satellite navigation system operated by the US Department of Defence. It essentially provides a subscription-free civilian timing and navigation service. GPS is primarily intended as a highly accurate global positioning and navigation ...
How To Synchronise Your Windows PC to a Time Server
Do you regularly need to correct the time on your PC? The answer is probably "Yes!". This is because computers have very poor time-keeping hardware. Often, the system clock in a regular PC can drift by minutes each day. However, help is at hand. It is ver...
Configuring a Simple NTP Time Server
NTP, or Network Time Protocol, is a standard protocol for synchronising time on computers and network equipment. NTP allows client computers to synchronise with a reference NTP server over a computer network. The protocol was originally developed for the ...
LF Radio NTP Servers: How to Decode the DCF-77 Time Broadcast
The DCF-77 radio time and frequency transmission is broadcast from Mainflingen near Frankfurt, Germany. The DCF-77 signal can be used by timing equipment to provide a precise time reference. Computer timing equipment, such as NTP server systems, which pro...
NTP Server Reference Clocks: What's Best Radio or GPS ?
A NTP Server is a network device that provides network servers and other network infrastructure with an accurate timing reference. A NTP Server obtains precise time from an external time source, such as radio time and frequency broadcasts or GPS. This art...
Network Time Protocol (NTP), Understanding Synchronisation.
Network Time Protocol seems to have been around for ever. In fact it is indeed one of the Internet's oldest protocols having been developed in the 1980's by Professor David Mills and his team from Delaware University.
In a laid-back world it perhaps do...
NTP Server - Receiving a Time Source
A NTP Server connects to a computer network with the purpose of synchronising all computers, routers and other devices to the exact same time. NTP servers use Network Time Protocol to adjust the drift of different machines to match the reference time.

NTP Server - Keeping Track of Time.
When you set your watch by the speaking clock or the radio beeps have you ever wondered who is responsible for setting that time and how they can be sure it is accurate.
This may seem like a straightforward question but their is no master clock that th...
Use a NTP Server To Keep Precise Network Time
Computers systems have internal real-time clocks that are notoriously poor at keeping accurate time. Hence, the time on all computers and network devices can drift away from one another at different rates. This can be a real headache when trying to synchr...
Using MSF as a Timing Reference for NTP Servers
Atomic clocks are incredibly expensive and generally they are normally only to be found in large scale physics laboratories such as MIT (Massachusetts Institute of Technology), NIST (National Institute of Standards and Technology (Colorado) or the Nationa...
Using WWVB as a Timing Reference for NTP Servers
Atomic clocks are incredibly expensive and generally they are normally only to be found in large scale physics laboratories such as MIT (Massachusetts Institute of Technology), NIST (National Institute of Standards and Technology (Colorado) or the Nationa...
Linux/Unix: Basic NTP Configuration
Network Time Protocol (NTP) is an Internet protocol used for the transfer of accurate time, providing time information so that a precise time can be obtained and maintained on a network
Most UNIX and Linux operating systems provide built-in time synchr...
Time Synchronisation with NTP
Network Time Protocol (NTP) is an Internet standard protocol designed over 25 years ago and still under constant development. NTP synchronises devises on a network to a single timing source. If time on a network is not synchronised when applications are c...
NTP Vandalism: Solutions to the Misuse and Abuse of NTP Servers
NTP servers, like most systems are open to abuse and misuse. NTP servers can be flooded with traffic (a distributed denial of service - DDoS attack), the server's access policy could be violated or the NTP rules of engagement drawn up to prevent misuse of...
