在Angular Material datepicker中本地化日期值

我正在使用Angular Material日期选择器。我的问题是，当我将日期发送到Web Api控制器时，我得到的日期小于在表单中选择的日期。我认为这是由于日期值未本地化的缘故。我想知道的是如何在角度js

I'm working with Angular Material date picker. My problem is that when I send a date to the Web Api controller, I get a date less than the date I have selected in my form. I think this is due to the fact that the date value is not being localized. What I want to know is that how to localize the date in angular js

HTML：

<div ng-controller="AppCtrl" style='padding: 40px;' ng-cloak>
  <md-content>
    <h4>Standard date-picker</h4>
    <md-datepicker ng-model="myDate" md-placeholder="Enter date"></md-datepicker>
</md-content>
</div>

控制器：

angular.module('datepickerBasicUsage',
    ['ngMaterial', 'ngMessages']).controller('AppCtrl', function($scope) {
  $scope.myDate = new Date();
  $scope.minDate = new Date(
      $scope.myDate.getFullYear(),
      $scope.myDate.getMonth() - 2,
      $scope.myDate.getDate());
  $scope.maxDate = new Date(
      $scope.myDate.getFullYear(),
      $scope.myDate.getMonth() + 2,
      $scope.myDate.getDate());
  $scope.onlyWeekendsPredicate = function(date) {
    var day = date.getDay();
    return day === 0 || day === 6;
  }
});
