<p class="Pp">The <code class="Nm">rtc</code> driver supports reading from and
    writing to the Atari real time clock (RTC). When reading from the RTC, the
    format string of the output, as described in the
    <a class="Xr">strftime(3)</a> manual page, is:</p>
<div class="Bd Pp Bd-indent Li">
<pre>``%Y%m%d%H%M.%S''</pre>
</div>
<p class="Pp">The same format is used to set the RTC to the current date. Note
    that the kernel expects the RTC to run in UTC.</p>
