Estou tentando analisar RSS2, Atom feeds usando objetos SyndicationFeed. Mas estou recebendo XmlExceptions ao analisar o campo DateTime como pubDate

2012-01-17 08: 01: 06

public static List<SyndicationItem> getRssData(string url)
{
    List<SyndicationItem> list = new List<SyndicationItem>();

    WebClient client = new WebClient();
    try
    {
        SyndicationFeed feed = SyndicationFeed.Load(XmlReader.Create(url));
        list = (from item in feed.Items select item).ToList();
    }
    catch (Exception e)
    {
        throw e;
    }

    return list;
}

O link da URLhttp: //news.163.com/special/00011K6L/rss_newstop.xm

<item id="2">
    <title>...</title>
    <link>...</link>
    <description>......</description>
    <pubDate>2012-01-17 12:09:29</pubDate><-----Exception
</item>

Existe uma maneira melhor de conseguir isso? Por favor ajude. Obrigado
