Time synchronization is the process of aligning the clocks of different devices or systems to ensure they all display the same time. This is crucial for various applications, such as computer networks, telecommunications, and financial transactions, where accurate timing is essential for coordination and data integrity. To achieve time synchronization, protocols like NTP (Network Time Protocol) are often used. These protocols allow devices to communicate with a reliable time source, such as an atomic clock or a GPS satellite, to adjust their internal clocks. This helps maintain consistency across systems, reducing errors and improving overall efficiency.
