datepicker: ng-model-options timezone option not handled properly

[JohnPlaisted]

Actual Behavior:

• What is the issue?
  The text for the date is correct but the date doesn't show up correctly in the Calendar. For me the date selected in the calendar is one day behind. I think this would be the case for users with a local time zone east of UTC. (a negative offset)
• What is the expected behavior?
  The dates should match

CodePen (or steps to reproduce the issue): *

• Details:
  The text for the date shows 11/15/2017, but the calendar selects 11/14/2017.
  I think this has to do with timezone adjustments.

AngularJS Versions: *

• AngularJS Version: 1.5.5
