A time server is a computer or device that provides accurate time information to other devices over a network. It synchronizes the clocks of computers and other devices, ensuring they all display the same time. This is crucial for various applications, including data logging, transaction processing, and network security. Time servers often use protocols like NTP (Network Time Protocol) to distribute time information. They can obtain time from reliable sources, such as atomic clocks or GPS satellites, and then share this information with connected devices. This synchronization helps maintain order and consistency in digital communications.
