<p>I think we should keep the date format matching, to avoid breaking compatibility with anything. I checked and a straightforward <code>json.date_created note.created_at.to_s</code> (and <code>to_s</code> for the other dates, of course) appears to be sufficient.</p>
<p>It would be good to move all the notes dates (including in the XML) to the same "xmlschema" format as the rest of the API, but let's make that part of the next API version.</p>
