title: How to save dates in local timezone to db with rails3?
body: <p>I have Rails3 application with model user and field expires_at created like this:</p>
  
  <pre><code>t.column :expires_at, :timestamp
  </code></pre>
  
  <p>In my database (postgresql) it has type: </p>
  
  <pre><code>timestamp without timezone
  </code></pre>
  
  <p>The problem is when I call:</p>
  
  <pre><code>@user.expires_at = Time.now
  @user.save
  </code></pre>
  
  <p>it is saved into database with UTC timezone (my local time is UTC + 1:00, Warsaw) but I don't want that. I just want to have time with my local timezone saved into the database (2011-03-30 01:29:01.766709, not 2011-03-29 23:29:01.766709)</p>
  
  <p>Can I achieve this using rails3?</p>
