Network Time Protocol (NTP) is a networking protocol used to synchronize the clocks of computers and devices over a network. It ensures that all systems have the same time, which is crucial for various applications, including logging events and coordinating tasks. NTP can synchronize time within milliseconds over the internet and even better in local networks. NTP operates by using a hierarchy of time sources, known as time servers. These servers provide accurate time information, often derived from atomic clocks or GPS systems. Clients request time updates from these servers, allowing them to adjust their clocks accordingly and maintain accurate timekeeping.
