title: Rails DateTime.now without Time
body: <p>I need to use DateTime.now to grab the current date, and "strip off" the time.</p>
  
  <p>For example, this shows what I <em>don't</em> want: <code>DateTime.now =&gt;  Sat, 19 Nov 2011 18:54:13 UTC +00:00</code></p>
  
  <p>This shows what I <em>do</em> want: <code>DateTime.now.some_operation =&gt; 2011-11-06 00:00:00 UTC</code></p>
