NTP versions

Since its first implementation, NTP has undergone a remarkable evolution that has made it one of the silent pillars of Internet reliability. Let's have a look at the different NTP versions, each with their own nuances and improvements that have led to more accurate and robust synchronization.

The Network Time Protocol has undergone significant developments since its introduction. Originally defined in RFC 958 in September 1985, NTP version 0 enabled time accuracy in the range of several tenths of a second. Three years later, in 1988, RFC 1059 introduced NTP version 1 (NTPv1). This version brought improvements and optimizations for use in client-server and peer-to-peer networks. These developments are part of the constant evolution of NTP to ensure precise and reliable time measurement in networks.
