title: IntlDateFormatter::Parse returns Date parsing failed: U_PARSE_ERROR
body: <p>I am using symfony2 for my application.  During date type form field validation symfony attempts to parse the string date value being passed in.  For some reason this works locally (running MAMP &amp; php 5.3.6) but fails on our remote fedora server. (php 5.3.8). Here's some detils, i'm including anything that <em>might</em> be relavent. </p>
  
  <p>When instantiating a new IntlDateFormatter I'm using </p>
  
  <pre><code>locale: en_US_POSIX
  date format: 2
  time format: -1
  timezone: America/Chicago
  calendar: 1
  pattern: MM-dd-yyyy
  </code></pre>
  
  <p>Parse is called on the IntlDateFormatter using a date like <strong>11/21/2012</strong></p>
  
  <pre><code>$timestamp = $this-&gt;getIntlDateFormatter()-&gt;parse($value);
  </code></pre>
  
  <p>and here's the getIntlDateFormatter method.</p>
  
  <pre><code>protected function getIntlDateFormatter()
  {
      $dateFormat = $this-&gt;dateFormat;
      $timeFormat = $this-&gt;timeFormat;
      $timezone = $this-&gt;outputTimezone;
      $calendar = $this-&gt;calendar;
      $pattern = $this-&gt;pattern;
  
      return new \IntlDateFormatter(\Locale::getDefault(), $dateFormat, $timeFormat, $timezone, $calendar, $pattern);
  }
  </code></pre>
  
  <p>the entire class that handles the transforming of string date values into localized datetime values is <a href="https://github.com/symfony/symfony/blob/master/src/Symfony/Component/Form/Extension/Core/DataTransformer/DateTimeToLocalizedStringTransformer.php" rel="nofollow noreferrer">here</a>...</p>
  
  <p>This results in the failed parse, the error is accessible using: intl_get_error_message()</p>
  
  <p>Here's some snippets from phpinfo() on the remote machine:</p>
