taiclock

## Name

taiclock — check a system's clock through TAICLOCK

## Synopsis

`taiclock` {`host`}

## Description

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.
