摘要: Abstract : This paper describes algorithms to discipline a computer clock source of standard time, such as GPS receiver or another synchronized source. The are designed for use in the Network Time Protocol (NTP), which is used synchronize clocks global Internet. They have been incorporated NTP software Unix and Windows and, highest accuracy, operating system kernels Sun, DEC, HP workstations. Rms errors on LANs usually less than 10 microsecond Internet paths 5 ms. However, rare disruptions one kind can cause error spikes up 100 ms paths.
