The NTP (Network Time Protocol) has since the early days of the Internet was responsible for the synchronization of time through computer networks. Not only is effective in this NTP, but when connected to a source of UTC (Coordinated Universal Time) NTP is also very accurate.
Most computer networks connected to UTC via a dedicated NTP time server. These devices use an external connection to an atomic clock to receive time and then distribute it through a network. By connecting externally, through GPS (Global Positioning System) or long wave radio, are not only incredibly accurate NTP servers are also very safe since it does not depend on an Internet connection at the time.
NTP Servers are also increasingly used for other innovations. Not only with traditional technologies such as CCTV, traffic signals, air traffic control and the stock market, they become dependent on time synchronization with time servers, but a growing number of modern technologies are too.
NTP time servers are now commonplace in modern digital signage systems (the use of flat screen televisions for advertising the home). These displays of the network are synchronized to allow scheduled and organized campaigns.
A digital signal synchronized campaign is a method to make a stand on the advertising of the season at home outside. This is increasingly important as more and more digital signature is carried out by a campaign of conventional digital signal difficult to recruit and attract attention.
By synchronizing multiple displays, together with an NTP server and run a program and date of the campaign. This allows content to be scheduled or planned to maximize impact.
Minor Servers can be installed directly in the digital signage LCD enclosure although like most of these devices require time synchronization or GPS longwave antenna signal can be problematic. A better solution is a digital signaling network and the use of a single NTP server as a method for synchronization.
NTP may be the oldest Internet protocol and NTP time servers have been around for almost two decades, but this relatively old technology and software has never been much in demand.

A Guide to Synchronising a Network With NTP
Network Time Protocol (NTP) is a TCP / IP was developed when the Internet was in its infancy. It was developed by David Mills of the University of Delaware who was trying to synchronize the computers over a network with a degree of accuracy.
NTP is a protocol based on UNIX, but has been ported to work as effectively on PCs and a version is included with operating systems from Windows 2000 (including Windows 7, Vista and XP).
NTP, and the devil (application) that controls it, not just a way to pass time around. Any system running an NTP daemon can act as a client to consult the reference time from other servers or that can make your own time available for other devices to use that actually makes it a time server itself. It can also act as an equal, to collaborate with others to find the source of more stable and accurate time for use.
One of the most flexible of NTP is hierarchical in nature. NTP devices divided into strata, each stratum level is defined by its proximity to the reference clock (atomic clock). The atomic clock itself is a stratum 0 device, the device closest to it (often a dedicated NTP time server) is a stratum 1 device while other devices that connect to the stratum 2. NTP can maintain accuracy within 16 levels of stratum.
Any network that must be synchronized, you must first identify and locate an NTP time source to distribute. Internet sources of time are available, but often you are made of layer 2 devices that operate through the firewall. The only way you can peer NTP time is if the TCP / IP port is left open to allow traffic through. This could lead to security issues such as malicious users can exploit this hole in firewall.
Dedicated servers NTP time finding a source of time through GPS or radio signals and so do not leave a network vulnerable to attacks. By adding an NTP time server to a network router and any of hundreds or even thousands of devices can be synchronized through the hierarchical structure of NTP.
