The Network Time Protocol (NTP) is more popular than the DAYTIME and TIME protocols because it is more accurate, secure, and widely supported. (Chet Hosmer, 2014) NTP utilizes the User Datagram Protocol (UDP) to communicate minimalistic timing packets communicated between a server and a client wishing to synchronize with that time source.
