<p>
This object implements a custom <a href="/usr/share/gtk-doc/html/gstreamer-0.10/GstClock.html"><span class="type">GstClock</span></a> that synchronizes its time
to a remote time provider such as <a class="link" href="GstNetTimeProvider.html" title="GstNetTimeProvider"><span class="type">GstNetTimeProvider</span></a>.
</p>
<p>
A new clock is created with <a class="link" href="GstNetClientClock.html#gst-net-client-clock-new" title="gst_net_client_clock_new ()"><code class="function">gst_net_client_clock_new()</code></a> which takes the
address and port of the remote time provider along with a name and
an initial time.
</p>
<p>
This clock will poll the time provider and will update its calibration
parameters based on the local and remote observations.
</p>
<p>
Various parameters of the clock can be configured with the parent <a href="/usr/share/gtk-doc/html/gstreamer-0.10/GstClock.html"><span class="type">GstClock</span></a>
"timeout", "window-size" and "window-threshold" object properties.
</p>
<p>
A <a class="link" href="GstNetClientClock.html" title="GstNetClientClock"><span class="type">GstNetClientClock</span></a> is typically set on a <a href="/usr/share/gtk-doc/html/gstreamer-0.10/GstPipeline.html"><span class="type">GstPipeline</span></a> with
<a href="/usr/share/gtk-doc/html/gstreamer-0.10/GstPipeline.html#gst-pipeline-use-clock"><code class="function">gst_pipeline_use_clock()</code></a>.
