title: how do i use date mutators or carbon in sql queries
body: <p>If i have a sql query returning from  DB::Select how can i return Carbon objects for my created_at attributes?</p>
  
  <p>i would like to be able to do something like:</p>
  
  <pre><code>$result = DB::select(DB::raw("SELECT X,Y,Z,tabletwo.created_at FROM tableone LEFT JOIN tabletwo ON tableone.X = tabletwo.foreignX"));
  
     foreach($result as $row)
     {
  
        $row-&gt;created_at-&gt;timezone(Auth::user()-&gt;timezone);
  
     }
  </code></pre>
  
  <p>I have already tried adding the fields into the getDates method on my models but it doesn't make a different- i assume since its a custom sql query and not returning an object.</p>
