<p><strong><code>date [url]</code></strong></p>
<p>The purpose of this command is to get the current date from a server and print it on stdout (http date format). This in useful in combination with the <code>-U</code> option for the <code>list</code> and <code>get</code> command.</p>
<p>The <em>url</em> can be any http url. If no <em>url</em> is specified, the local time is used.</p>
<h3 id="example-incremental-dav-get">Example: incremental dav get</h3>
<p>It is possible to download only resources, which are modified since a specified date. The <em>date</em> command allows you to easily store the date of the last <em>get</em>.</p>
<pre><code>$ dav get -R myserv/col/
...
$ dav date myserv &gt; last_get</code></pre>
<p>After some resources are changed on the server, you can download only the modified files.</p>
<pre><code>$ dav get -R -U `cat last_get` myserv/col/</code></pre>
