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 provides accurate timekeeping by coordinating time across servers and clients, typically achieving millisecond precision over the public internet. NTP servers are dedicated systems that distribute time information to clients, ensuring consistent timestamps for logging, security, and distributed applications.
Developers should learn and use NTP servers when building systems that require precise time synchronization, such as financial transactions, logging in distributed environments, or security protocols like Kerberos. It is essential for debugging time-sensitive issues, ensuring compliance with regulations that mandate accurate timestamps, and maintaining consistency in databases and event ordering across servers.
