title: Parse RSS pubdate to DateTime
body: <p>I get this date string from an RSS:</p>
  
  <blockquote>
    <p>Wed, 16 Dec 2015 17:57:15 +0100</p>
  </blockquote>
  
  <p>I need to parse into a DateTime. Ive googled and searched stack overflow and gotten to the following answer (ive tried with only one, two and four 'z' instead of three)</p>
  
  <pre><code>string parseFormat = "ddd, dd MMM yyyy HH:mm:ss zzz";
  DateTime date = DateTime.ParseExact(dateString, parseFormat,
                                      DateTimeFormatInfo.CurrentInfo,
                                      DateTimeStyles.None);
  </code></pre>
  
  <p>But I get this error: </p>
  
  <blockquote>
    <p>System.FormatException: String was not recognized as a valid
    DateTime.</p>
  </blockquote>
