For ‘date’ data types:  
Is it permissible to use a date-only format (e.g. yyyy-mm-dd), or is a full Datetime (yyyy-mm-ddThh:mm:ss) required?

Hi Kim,

It’s possible to use either the `yyyy-mm-dd` format or the combined date & time in UTC. 🙂

ex. `<meta class="swiftype" name="published_at" data-type="date" content="2017-06-20" />`
