Network Time Protocol (NTP) is an essential component of modern networking, ensuring precise synchronisation of clocks across systems, whether over local networks or the internet.
Developed in the 1980s by Dr David Mills at the University of Delaware, NTP is one of the oldest networking protocols still in active use. Its fundamental aim is to align all participating devices to Coordinated Universal Time (UTC), thereby making operations reliable and keeping data integrity across networks. It’s worth noting that Dr Mills, who passed away in January 2024, is fondly remembered as the internet’s “father time” for his work on NTP.
