An in-depth insight into stratum levels and their connection with Network Time Protocol (NTP).
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.
In this article, NTP time server specialists Galleon Systems, answers the question what is network time protocol? Additionally, the article explains the benefits of NTP for businesses, plus the part it plays in day to day life.
UTC is an atomic clock time reference used to ensure all PCs and computer networks, no matter where they are in the world, are all running the same time. NTP time servers are used to receive a times source and distribute it around a network but there are various choices for locating a source of UTC for time reference for synchronisation.
Ethernet NTP digital wall clocks plug into an NTP times server using an Ethernet cable. This means that the time signal is sent from the NTP time server directly to the Ethernet NTP digital wall clock, maintaining its accuracy. The Ethernet digital wall clock never needs setting as it is automatically set by the time signal sent from the times server, which means it will always be accurate, and the Ethernet NTP digital wall clock requires no mains power or batteries as it gets its power form the Ethernet.
NTP POE wall clocks use Network Time Protocol (NTP) to maintain accuracy and synchronisation. NTP is a computer algorithm that works by taking a single master time source that it distributes to all devices on a network. In the case of most NTP systems, the time is received via a NTP time server that is hooked up to a computer network.
There are various solutions for synchronised office clocks, suitable for use in offices of all sizes, even those spread out across the country. The simplest solution is to use atomic clock radio receiver clocks. These come with either digital or analogue displays and they use radio transmissions to receive a source of atomic clock time (UTC – Coordinated Universal Time).
The big advantage of a digital network wall clock is that they never have to be set as the time is kept and maintained by the network time server, which ensure the wall clock is accurate to the millisecond. Furthermore, most digital network wall clocks use the power over Ethernet system to provide the clock’s power, so there is no need to wire them up to the mains or install batteries
Because health care is based on multi-disciplinary teams, treatments, meetings, operations and procedures often require strict coordination to prevent wasting time and provide an efficient service. Making sure everybody has access to a synchronised and accurate time is part of this process, which is what makes precise and reliable digital wall clocks for hospitals so important.
A business digital wall clock can use an atomic clock as a source of time, and relay this time in a digital display. These atomic clock receiving clocks come in various guises. Some use small radio receivers to pick up the atomic clock transmissions broadcast by the National Physical Laboratory (NPL) in the UK or the National Institute of Standards and Time (NIST) in the USA
