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 data logging, where accurate timing is essential for coordination and data integrity. Methods for time synchronization include using protocols like NTP (Network Time Protocol) and GPS (Global Positioning System). These systems help maintain consistent time across devices, reducing discrepancies that can lead to errors in communication and data processing. Accurate timekeeping is vital for security, transaction logging, and event scheduling.
