title: Rails 2.3.5 I18n month/day name translation problem
body: <p>My <code>config/locales/pl.yml</code> file (sampled from <a href="http://github.com/svenfuchs/rails-i18n/blob/master/rails/locale/pl.yml" rel="noreferrer">here</a>):</p>
  
  <pre><code>pl:
    date:
      day_names: [Niedziela, Poniedziałek, Wtorek, Środa, Czwartek, Piątek, Sobota]
      month_names: [~, Styczeń, Luty, Marzec, Kwiecień, Maj, Czerwiec, Lipiec, Sierpień, Wrzesień, Październik, Listopad, Grudzień]
  </code></pre>
  
  <p>In <code>script/console</code>:</p>
  
  <pre><code>I18n.locale = 'pl'
  =&gt; "pl"
  
  Time.now.strftime("%A, %B")
  =&gt; "Tuesday, August"
  </code></pre>
  
  <p>Why? Or put it another way - how can I get translated month names? I'll also note that the locale file is definitely read as it includes a bunch of other translations, which all work.</p>
