title: Entity Framework losing Sql DateTime precision
body: <p>I am querying my EDM using Entity SQL and am losing millsecond precision on my DateTime values. For example 2011/7/20 12:55:15.333 PM gets changed to 2011/7/20 12:55:15.000 PM.</p>
  
  <p>I have confirmed that in SQL the milliseconds are recorded precisely.</p>
  
  <p>There is a Precision attribute I can apply in the .edmx XML file, but I do not know what sort of values it takes, </p>
  
  <pre><code>      &lt;Property Name="Timestamp"
                  Type="DateTime"
                  Nullable="false"
                  Precision="???" /&gt;
  </code></pre>
  
  <p>Does anyone know how to use this precision attribute ?</p>
  
  <p>Thanks. </p>
