The Paris Observatory has announced an additional leap second will be added to clocks in June 2015. What does this mean for businesses? Galleon Systems examines.

Unsynchronised clocks are a network security hazard and, believe it or not, time discrepancies can lead to major breaches, causing untold disruption. What are the problems that can arise and how do you maintain time synchronisation? Find out here…
Accurate time specialists, Galleon Systems, assess the implications of NIST’s new atomic clock.
NIST (National Institute of Standards and Technology) has revealed a new atomic clock, claiming that it has the capability to maintain accurate time for the next 300 million years.
NTP time server specialists, Galleon, answers what is NTP? Highlighting the benefits of NTP servers for businesses.
What Is NTP?
In simple terms NTP, or Network Time Protocol, is a system used to synchronise the time of day across computer networks. Originally developed by David L. Mills of the University of Delaware, NTP works by using a single time source, enabling it to synchronise time across all devices that are part of a network.
Did you know? NTP was first implemented in 1985. However, some of its predecessors date back as far as 1979.
Specialists in the design, manufacture and supply of time synchronisation units and digital clocks, Galleon Systems clears up the confusion over the impact of daylight savings time on NTP time servers.
In March, clocks in the UK go forward one hour in preparation for British summer time, prompting concerns that daylight savings time will cause problems for users of NTP time servers. In a bid to reassure, Galleon Systems clarifies the impact of daylight savings time on NTP time servers in order to calm such concerns.
London 2012 will be the 30th modern Olympic Games, and in its 116-year history, UY98UZDDVGGJ the Olympics have gone through many changes. New events have been introduced, records have been broken and different cities have played host to the games, but one constant has remained – the need to time competitors accurately during the different events.

All sorts of technologies rely on precise and exact time, from cash machines and CCTV cameras, to speed cameras and computer networks. For computer networks, accurate time is essential for preventing errors, fraud and ensures security. Without it, many organisations, industries and modern applications couldn’t function. Everything from internet banking to air traffic control relies on precise and accurate time, but many organisations take unnecessary risks when it comes to the time on their networks and rely on online time servers.

Accurate time is important for many organisations, but keeping precise time in a school, office or business can be a challenge. Standard clocks are not as reliable as most people think. Often, battery powered quartz clocks will drift, sometimes by several minutes a week, which affects the timekeeping of people. (more…)
GPS time servers are a highly accurate and secure method of synchronising a computer network to UTC (Coordinated Universal Time). GPS time servers are simple to use and ensure a network is synchronised to s secure form of time. However, many network administrators don’t see the need to use a GPS time server and continue to put their network at risk by using an online source of time for synchronisation. Here are five reasons why a GPS time server is crucial for computer network synchronisation. (more…)
Time synchronisation is something easily taken for granted in this day and age. With GPS NTP servers, satellites beam down time to technologies, which keeps them synced to the world’s time standard UTC (Coordinated Universal Time).
Before UTC, before atomic clocks, before GPS, keeping time synchronised was not so easy. Throughout history, humans have always kept track of time, but accuracy was never that important. A few minutes or an hour or so difference, made little difference to people’s lives throughout the medieval and regency periods; however, come the industrial revolution and the development of railways, factories and international commerce, accurate timekeeping became crucial.
Greenwich Mean Time (GMT) became time standard in 1880, taking over from the world’s first time standard railway time, developed to ensure accuracy with railway timetables. Soon, all businesses, shops and offices wanted to keep their clocks accurate to GMT, but in an age before electrical clocks and telephones, this proved difficult.
Enter the Greenwich Time Lady. Ruth Belville was a businesswoman from Greenwich, who followed in her father’s footsteps in delivering time to businesses throughout London. The Belville’s owned a highly accurate and expensive pocket watch, a John Arnold chronometer originally made for the Duke of Sussex.
Every week, Ruth, and her father before her, would take the train to Greenwich where they would synchronise the pocket watch to Greenwich Mean Time. The Belvilles would then travel around London, charging businesses to adjust their clocks their chronometer, a business enterprise that lasted from 1836 to 1940 when Ruth finally retired at the age of 86.
BY this time, electronic clocks had began to take over traditional mechanical devices and were more accurate, needing less synchronisation, and with the telephone speaking clock introduced by the General Post Office (GPO) in 1936, timekeeping services like the Belville’s became obsolete.
Today, time synchronisation is far more accurate. Network time servers, often using the computer protocol NTP (Network Time Protocol), keep computer networks and modern technologies true. NTP time servers receive an accurate atomic clock time signal, often by GPS, and distribute the time around the network. Thanks to atomic clocks, NTP time servers and the universal timescale UTC, modern computers can keep time to within a few milliseconds of each other.
