It can also operate as an NTPv4 (RFC 5905) server and peer+to provide a time service to other computers on the network.++It's designed to perform well even under adverse conditions: congested+networks, unreliable clocks drifting with changes in temperature, and devices+or virtual machines that are frequently turned off and connect to the Internet+for only a few minutes at a time.++Typical accuracy when synchronised over the Internet is several milliseconds.+On a local network this can reach tens of microseconds. With hardware+time-stamping or reference clock, sub-microsecond accuracy is possible.")+ (license l:gpl2)))+ (define-public ntp (package (name "ntp")-- 2.25.2
