New Technologies And The Growing Importance Of Time Synchronisation
The NTP protocol (Network Time Protocol) has since the earliest days of the internet been responsible for synchronising the time across computer networks. Not only is NTP effective at this, but when connected to a source of UTC (Coordinated Universal Time) NTP is also extremely accurate.
Most computer networks connect to UTC via a dedicated NTP time server. These devices use an external connection to an atomic clock to receive the time and then distribute it across a network. By connecting externally, via GPS (Global Positioning System) or long wave radio, not only are NTP servers incredibly accurate but they are also very secure as they don’t rely on an internet connection for the time.
