title: How to publish a collection in Meteor that just sends the last 24 hours of data to the client?
body: <pre><code>Meteor.publish('mountCarmelData', function dataPublication(){
      return MountCarmel.find({}, 
      {
          sort: {created_at: -1}
      });
  });
  </code></pre>
  
  <p>Is there any way to limit this publication to publish only the past 24 hour of data? I have a timestamp on each record called 'created_at'.</p>
