title: nullable datetimes
body: <p>I have 1 datetime field that is not nullable and 1 that is nullable.  I can use the following code with the non nullable one :</p>
  
  <pre><code> c.StartDate.Day.ToString() + "/" + 
   c.StartDate.Month.ToString() + "/" + 
   c.StartDate.Year.ToString()
  </code></pre>
  
  <p>But when I try to do this with the nullable one, I get the error :</p>
  
  <blockquote>
    <p>'System.Nullable' does not contain a definition for 'Day' and no extension method 'Day' accepting a first argument of type 'System.Nullable' could be found (are you missing a using directive or an assembly reference?)</p>
  </blockquote>
  
  <p>How do I get the Day, Month, Year of a nullable datetime?</p>
