<h1> The <tt>s6-clock</tt> program </h1>
<p>
s6-clock gets or sets the system clock.
</p>
<h2> Interface </h2>
<pre>
s6-clock [ <em>label</em> ]
</pre>
<p>
When called without an argument, s6-clock writes the current system
time, as a
<a href="http://skarnet.org/software/skalibs/libstddjb/tai.html#timestamp">TAI64N
timestamp</a>, to stdout.
</p>
<p>
When given an argument <em>label</em>, which must be a
<a href="http://skarnet.org/software/skalibs/libstddjb/tai.html#timestamp">TAI64N
timestamp</a>, s6-clock sets the system time to this value.
</p>
<h2> Notes </h2>
<p>
s6-clock only prints or accepts TAI time, no matter what the system clock is set
to (TAI-10 or UTC); it will automatically make the right conversions for your
system clock. Make sure your
<a href="http://skarnet.org/software/skalibs/">skalibs</a> has been built with
the right settings.
