NTPv4

NTPv4, or Network Time Protocol version 4, is a system that helps computers keep their clocks synchronized over the internet or local networks. Accurate timekeeping is crucial for many applications, like financial transactions and data logging. NTPv4 works by having devices communicate with reliable time servers to adjust their clocks, ensuring they stay in sync with one another. It can adjust for varying network delays and is designed to be secure and efficient, making it a critical component for maintaining time accuracy in modern digital communication and computing environments.
