title: OData DateTime filter Edm.String error?
body: <p>I am writing an DateTime filter query in OData like this:</p>
  
  <pre><code>... + "$filter=SubmitTime lt datetime'2014-12-30T23:59:59.99Z'"
  </code></pre>
  
  <p>and met the following error:</p>
  
  <p><img src="https://i.stack.imgur.com/DIdMx.png" alt="enter image description here"></p>
  
  <p>I did follow the OData format guideline and other online references, and the string I wrote is aligned with the guideline.</p>
  
  <p>So is this a problem caused by dll version? like stated in this post:
  <a href="https://stackoverflow.com/questions/13978514/webapi-odata-datetime-error">WebAPI OData DateTime error</a></p>
  
  <p>The Microsoft.OData.Edm.dll version I am using is:
  <strong>Runtime Version: v4.0.30319
  Version: 6.3.0.0</strong></p>
  
  <p>Any ideas?
  Thanks!</p>
