RFC 5905 (Network Time Protocol Version 4)

RFC 5905 outlines the specifications for Version 4 of the Network Time Protocol (NTP), which is used to synchronize clocks over computer networks. It ensures that devices have accurate time, which is crucial for various functions like logging events, scheduling tasks, and security. The document describes how NTP operates, including methods for obtaining time from reliable sources, managing network delays, and improving synchronization accuracy. It also addresses security considerations to prevent attacks, making NTP more robust and efficient for modern internet applications. Overall, it helps maintain precise timekeeping in our interconnected world.
