• Using Time and Frequency Transmissions to Synchronise a Computer Network Computer network synchronisation is often perceived as a headache for many system administrators but keeping accurate time is essential for any network to remain secure and reliable. Failing to have an accurate synchronised network can lead to all sorts of errors when dealing with time sensitive transactions. The protocol NTP (Network Time Protocol) is the industry standard for time synchronisation. NTP distributes a single time source to an entire network ensuring all machines are running the exact same time. One of the most problematic areas in synchronising a network is in the selection of the time source. Obviously if you are spending ...
  
  
• Selecting a Time Source Check List In selecting a timing source to synchronise a computer network to using a NTP server (Network Time Protocol) it is important that the time source is accurate, secure and a source of UTC (Coordinated Universal Time). UTC is a global timescale used by computer networks, business and commerce across the globe. Whilst UTC is freely available across the Internet it is neither accurate nor secure (being as it is external to your firewall).  Also Internet time sources cannot be authenticated which is NTP’s own method of ensuring a time source is what it says it is. There are two secure, accurate ...

• Selecting a NTP Time Server In selecting a NTP time server the things to think about  are where the device will be located and which timing reference would be most suitable for the applications it is required for. There are benefits and drawbacks to both the radio broadcasts and the GPS timing signals that are commonly used in these servers. Not every country transmits a national time and frequency broadcast which means if a time server is to be located outside of the US, Japan, Germany, the UK or France it is doubtful that a signal  will be received (although some of these broadcasts can be ...
  
  
• NTP Time Server Frequently Asked Questions Q. What is NTP? A. NTP – Network Time Protocol is an Internet protocol for time synchronisation, whilst other time synchronisation protocols are available NTP is by far the most widely used having been around since the mid 1980’s when the Internet was still in its infancy. Q. What is UTC? A.  UTC – Coordinated Universal Time is a global timescale based on the time told by atomic clocks. Because these clocks are so accurate every year or so ‘leap seconds’ have to be added as UTC is even more accurate than the Earth’s rotation which slows and speeds up thanks to the ...
