title: Is it possible to save datetime to DynamoDB?
body: <p>I have the next code:</p>
  
  <pre><code>users_table = Table(users_table_name, connection=Core.aws_dynamodb_connection)
  users_table.put_item(data={
    "login": login,
    "password": hashlib.sha256(password.encode("utf-8")).hexdigest(),
    "profile": profile,
    "registration_date": datetime.now() # PROBLEM IS HERE
  })
  </code></pre>
  
  <p>But when I run it, it fails with error:</p>
  
  <blockquote>
    <p>TypeError: Unsupported type "&lt; type 'datetime.datetime' >" for value "2015-01-12 05:02:57.053131"</p>
  </blockquote>
  
  <p>I've tried a lot of ways, but it seems that it isn't possible to save <code>datetime</code> to DynamoDB. Btw it works fine in MongoDB.</p>
  
  <p>Is there any solution?</p>
