Converting DXL timestamp to C# DateTime <p>totally messed up with Lotus Notes DXL timestamp format... Given is a timestamp of an exported DXL from a Lotus Notes document, which looks like that:</p> <pre><code>20141104T132939,49+01 </code></pre> <p>Trying to get the format working with <code>DateTime.ParseExact</code>, like:</p> <pre><code>DateTime.ParseExact(dateStr.Substring(0, 13), "yyyyMMddThhmm", System.Globalization.CultureInfo.InvariantCulture).ToString("dd.MM.yyyy hh:mm"); </code></pre> <p>But with no luck >>> <code>System.FormatException "no valid DateTime format"</code>.</p> <p>Can C# handle the above timestamp as it is?</p>
