taiclock4d 1 user commands djbwares taiclock4d announce the system's clock through TAICLOCK taiclock4d taiclock4d is identical to taiclockd1 except that it expects a UDP/IPv4 socket or an IPv4 adddress in the IP environment variable. taiclockd1 is capable of handling both IPv4 and IPv6 requests on combined-stack systems, and it is not necessary to use taiclock4d on such systems. taiclockd was originally part of Daniel J. Bernstein's clockspeed toolset in 1998. Original code and documentation by Daniel J. Bernstein. Documentation modernizations by Jonathan de Boyne Pollard.
