 <p>When you create your documents, you must set the creation date:</p> <pre><code>MyCollection.insert({ text: "abc", createdAt: new Date() }); </code></pre> <p>then, you can filter your data:</p> <ol> <li><p>If you want the documents created in an interval:</p> <p><code>MyCollection.find( {createdAt: { $gte: new Date("Sat Jul 30 2016 8:00:00"), $lt: new Date("Sat Jul 30 2016 9:00:00"), }}, {sort: {createdAt:1}});</code></p></li> <li><p>Or documents created exactly at 8am:</p> <p><code>MyCollection.find({createdAt: new Date("Sat Jul 30 2016 8:00:00")});</code></p></li> </ol> <p>Hope it helps.</p>
