Welcome to the home of the Network Time Protocol (NTP) Project. The NTP Project conducts Research and Development in NTP, a protocol designed to synchronize the clocks of computers over a network to a common timebase. NTP is what ensures the reliability of billions of devices around the world, under the sea, and even in space. This value is the correction that is applied to a client clock in order to synchronize it. A positive value indicates the server clock is higher. A negative value indicates the client clock is higher. disp. Dispersion, reported in seconds, is the maximum clock time difference that was ever observed between the local clock and server clock.You will need to find the following line within this file. This line is where the NTP servers are defined. #FallbackNTP=0.debian.pool.ntp.org 1.debian.pool.ntp.org 2.debian.pool.ntp.org 3.debian.pool.ntp.org Replace that line with the following, changing the NTP servers to the ones you want to utilize.
