You could do on following manner

    [Test]
    public void Test()
    {
        XElement root = XElement.Load("Data.xml");
        root.Descendants()
           .Where(x => x.Name.LocalName == "displayDateTime")
           .ToList()
           .ForEach(x => x.ReplaceNodes(GetDate(x)));
    }

    private static DateTime GetDate(XElement element)
    {
         return DateTime.Today.Add(DateTime.Parse(element.Value).TimeOfDay);
    }
