Maintaining accurate and synchronised time has never been so important for businesses and organisations. In today’s world, where so many transactions take place online, having a synchronised and accurate network time is crucial for businesses, especially those organisations that conduct their business over the internet or with other computer networks.
The accuracy of modern Olympic timing is made possible with the use of high quality timing devices, accurate synchronisation and atomic timing. Regular quartz oscillators are fairly accurate, but they still drift, which means without regular synchronisation, their accuracy would falter UY98UZDDVGGJ . To ensure all timing devices can achieve millisecond accuracy and precise synchronisation with one another, all Olympic timing devices are synchronised with GPS atomic clocks several times a day.
A GPS time server is ideal for preventing costly leap seconds that interrupt businesses that operate on a global timescale.
For computer networks, accurate time is essential for preventing errors, fraud and ensures security. 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 instead of a dedicated NTP server
NTP GPS time servers are becoming an essential tool for business networks. With the ability to synchronise hundreds of computer, switches and routers, an NTP GPS time server can keep a network accurate to within a few milliseconds of UTC (Coordinated Universal Time).
As the name suggests, GPS time servers receive their time from the GPS system (Global Positioning System). The GPS signal is basically just a time code sent down from the satellites’ onboard atomic clocks. This time signal is what satellite navigation systems use to triangulate positioning, but because it is generated by atomic clocks is extremely accurate and precise.
When it comes to network time synchronisation, Network Time Protocol (NTP) is by far the most widely used software protocol. Whether it’s for keeping a network of hundreds or thousands of machines synchronised, or keeping a single machine running true, NTP offers the solution. Without NTP, and the NTP server, many of the tasks we perform on the internet, from shopping to online banking, simply wouldn’t be possible.
Perhaps the safest and most accurate means of obtaining a time source is by utilising the time codes transmitted by the GPS (Global Positioning System). All that is required for picking up these GPS signals is a GPS NTP server, which will not only receive the time code, but also distribute it around the network, check for drift and maintain stable and precise time on all machines.
To synchronise a computer network or other technology systems to GPS time, all that is required is a GPS network time server. GPS network time servers are simple to install, simple to use and can maintain accuracy for all sorts of technologies. Used by organisations as diverse as stock exchanges, air traffic control and banking systems, GPS time servers provide an efficient and cost effective solution to maintain network synchronicity.
Most of us think we know what the time it is. At a glance of our wristwatches or wall clocks, we can tell what time it is. We also think we have a pretty good idea of the speed time move forwards, a second, a minute, an hour or a day are pretty well-defined; however, these units of time are completely man-made and are not as constant as we may think.
Time is an abstract concept, while we may think it is the same for everybody, time is affected by its interaction with the universe. Gravity, for instance, as Einstein observed, has the ability to warp space-time altering the speed in which time passes, and while we all live on the same planet, under the same gravitational forces, there are subtle differences in the speed in which time passes.
Using atomic clocks, scientists are able to establish the effect Earth’s gravity has on time. The high above sea level an atomic clock is placed, the quicker time travels. While these differences are minute, these experiments clearly demonstrate that Einstein’s postulations were correct.
Atomic clocks have been used to demonstrate some of Einstein’s other theories regarding time too. In his theories of relativity, Einstein argued that speed is another factor that affects the speed at which time passes. By placing atomic clocks on orbiting spacecraft or aeroplanes travelling at speed, the time measured by these clocks differs to clocks left static on Earth, another indication that Einstein was right.
Before atomic clocks, measuring time to such degrees of accuracy was impossible, but since their invention in the 1950’s, not only have Einstein’s postulations proved right, but also we have discovered some other unusual aspects to how we regard time.
While most of us think of a day as 24-hours, with every day being the same length, atomic clocks have shown that each day varies. Furthermore, atomic clocks have also shown that the Earth’s rotation is gradually slowing down, meaning that days are getting slowly longer.
Because of these changes to time, the world’s global timescale, UTC (Coordinated Universal Time) needs occasional adjustments. Every six months or so, leap seconds are added to ensure UTC runs at the same rate as an Earth day, accounting for the gradual slowing down of the planet’s spin.
For technologies that require high levels of accuracy, these regular adjustments of time are accounted for by the time protocol NTP (Network Time Protocol) so a computer network using an NTP time server is always kept true to UTC.
