taiclock 1 user commands djbwares taiclock check a system's clock through TAICLOCK taiclock host taiclock connects to a TAICLOCK server on host. It communicates using the TAICLOCK protocol. host must be a dotted-decimal IPv4 address, or the value 0 which is translated to the IP address 127.0.0.1. taiclock prints to its standard output a 16-byte TAI64NA adjustment that, when added to the local UNIX clock, will produce the TAI clock on host. This is suitable for input to programs such as clockadd1 and clockview1. taiclock limits the adjustment to 2 days. sntpclock1 a similar program that uses the SNTP protocol taiclockd1 a server program that speaks the TAICLOCK protocol clockspeed1 taiclock 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.
