taiclock — check a system's clock through TAICLOCK
taiclock {server}
taiclock connects to a TAICLOCK server on server.
It communicates using the TAICLOCK protocol.
server must be a dotted-decimal IPv4 address, a hexadecimal IPv6 address, a domain name that after name qualification the DNS maps to at least 1 IP address, or the value 0 which is translated to the IPv4 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 server.
This is suitable for input to programs such as clockadd(1) and clockview(1).
taiclock limits the adjustment to 2 days.
