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 clockadd(1) and clockview(1).
taiclock limits the adjustment to 2 days.
