Datepicker minDate and maxDate don't work properly with ng-model-options timezone

[antch]

Bug description:

When using date-picker-popup with an ng-model-options timezone set, the minDate and maxDate don't seem to be working properly. For example, if I set minDate to be 2016-12-31T00:00:00Z it allows selection of Dec 30th 2015. If I set maxDate to be 2016-01-15T00:00:00Z it only allows selection up to Jan 14th 2016.

Link to minimally-working plunker that reproduces the issue:

Notice how you are allowed to select outside of the minDate and maxDate that is set.

Version of Angular, UIBS, and Bootstrap

Angular: 1.5.x

UIBS: 2.1.3 (originally encountered on 1.3.3)

Bootstrap: 3.x

After further investigation it seems that the ngModelOptions isn't propagating from the popup to the picker. The workaround would be to put the ngModelOptions on a parent of the input field (the <div class="col-md-6"... in the linked plnkr) in which case Angular propagates that down to all child models.

Unfortunately this work-around doesn't work in uibs v1.3.3. I cannot upgrade to 2.1.3 because the timezone calculation seems to be broken for the model. In the plunker if you select a date after the initial load, it sets the time to 10AM and not midnight.
