NTP is an internet protocol that’s used to synchronise the clocks on computer networks to within a few milliseconds of universal coordinated time (UTC). It enables devices to request and receive UTC from a server that, in turn, receives precise time from an atomic clock. Script Summary. Gets the time and configuration variables from an NTP server. We send two requests: a time request and a "read variables" (opcode 2) control message. Without verbosity, the script shows the time and the value of the version, processor, system , refid, and stratum variables. With verbosity, all variables are shown.B=120. Client determines the time spend on the network is B-A- (Y-X)=120-100- (160-150)=10 seconds. Client assumes the amount of time it took for the response to get from the server to the client is 10/2=5 seconds. Client adds that time to the "true" time when the server sent the response to estimate that it received the response at "true" time ...The new kid on the block today is NTP.
