Catalogue – NTP Network Time Server
The global positioning system (GPS) can be used by GPS time servers as a source of very accurate time for the synchronization of computer networks. The GPS system has been in operation for a number of years. It is primarily used for positioning and marine navigation. However, it can also be used as a source of very accurate time.
The synchronization of computers in an organization can be of paramount importance. Additionally, in many environments a large wall mounted display of accurate time is also required.
Organisations need an accurate display of time. Schools, Colleges and Universities need to ensure lessons start at the correct time. Also, Companies need to ensure that meetings commence at an agreed time. Many organisations also need to accurately log events. Hospitals may need to know exactly when a patient requires medicine or to log the time of events associated with patients.
The synchronization of time on computers and networks is often vitally important. Without it, the time on individual computers will slowly drift away from each other at varying degrees until potentially each has a significantly different time. In systems that rely on ordered events occurring at specific times or logging of events, this can be a real problem. For instance, transactions generated by a computer with a system time slower than another computer may log a transaction as being received before the other computer even though it was generated after it.
