Fields with day-level granularity occurring at midnight when using iCal Fields row plugin

Steps to Reproduce

1. Install Drupal and Date iCal+dependencies
2. Add a Date field to a content type, collecting only Year/Month/Day
3. Create a View of content, with two displays: (attached is a view export assuming field_date attached to Page content type)
   1. Feed; style plugin iCal Feed, row plugin iCal Entity
   2. Feed; style plugin iCal Feed, row plugin iCal Fields
4. Create a piece of content using aforementioned date field.
5. The display using entities treats the date field as an all-day event, as expected:
   

   BEGIN:VEVENT
   ...
   DTSTART;VALUE=DATE:20150325
   DTEND;VALUE=DATE:20150326
   ...
   END:VEVENT
   

6. The display using fields, however, treats the date as occurring at 12:00 AM. The expected behavior was that this would also be treated as an all-day event.

   BEGIN:VEVENT
   ...
   DTSTART:20150325T000000Z
   DTEND:20150325T000000Z
   ...
   END:VEVENT
