Think you need to do it like this:

parser = new DOMParser();
var doc = parser.parseFromString(responseText, "text/html");

var dateTime = doc.querySelector("td.dateTime").innerHTML;

and set class="dateTime" on <td>

From MDN on DOMParser

In modern browsers you can also set xhr.responseType = "document" and directly get a document as result from the XHR.
