Md-datepicker timezone issue

I have a timezone problem with md-datepicker

.

I have this element:

HTML

:

<md-datepicker name="indate" md-placeholder="In Date" ng-model="fechain" ng-model-options="{ timezone: timezone }" md-min-date="fechain" md-max-date="fechain" required></md-datepicker>

      

        
        
        
      

    

And this is the view related part of the controller:

$scope.fechain = $scope.fechaminin = moment().toDate(); //Wed Jun 21 2017 21:10:59 GMT-0500 (-05)
$scope.timezone = moment().format('ZZ'); // "-0500"

      

        
        
        
      

    

But the datapicker shows June 22nd. I searched on Google but couldn't find any solution.

Any ideas?
