Diffbot attempts to normalize content in the Article API’s
date field. For example, the date:
February 5, 2014 will be returned in the Article API JSON response as:
"date": "Wed, 5 Feb 2014 00:00:00 GMT"
If a timestamp is available, the Article API will return the time converted to GMT. Articles without a timestamp will be returned with a timestamp of midnight GMT.
Date normalization will also occur for any Article API date fields using custom rules.
