NTP

NTP (Network Time Protocol) is a networking protocol used to synchronize the clocks of computer systems over packet-switched, variable-latency data networks. It ensures accurate timekeeping across devices, which is critical for logging, security, and distributed systems. Time servers implement NTP to provide a reliable time source for clients.

Also known as: Network Time Protocol, Time Server, NTP Server, Time Sync, Clock Synchronization

Why learn NTP?

Developers should learn NTP when building systems that require precise time coordination, such as financial transactions, event logging, or distributed databases, to prevent issues like data inconsistencies or security vulnerabilities. It is essential in cloud environments, IoT networks, and any application where time-sensitive operations occur across multiple machines.
