Unexpected behavior in the AngularJS UI Bootstrap datepicker causing dates to shift

Hi there, I have encountered an issue with setting the default date format (YYYY-MM-DD) in the UI Bootstrap datepicker input field using momentjs. Everything seems to display correctly until I try to console log the selected date. It appears that an additional day is being added along with a timezone (T00:00:00.000Z). Here's a snippet of my HTML code:

<div class="row">
                <div class="col-md-6">
                    <label>Drawdown Ent. Date <span style="color: red;">*</span></label>
                    <input type="text" 
                           class="form-control" 
                           datepicker-popup="yyyy-MM-dd" 
                           ng-model="bookloan.drawdown_ent_date" 
                           is-open="drawdown_ent_date.open" 
                           ng-click="drawdown_ent_date.open = true" 
                           datepicker-options="entDateOptions" 
                           date-disabled="disabled(date, mode)" 
                           close-text="Close" />
                </div>
            </div>

And here is a piece of my JavaScript code:

$scope.bookloan.drawdown_ent_date = moment().format("YYYY-MM-DD");

I'm puzzled as to what could be causing this discrepancy. Any insights would be greatly appreciated. Thank you.

My problem was resolved thanks to the implementation of this specific directive:

app.directive('datepickerLocalDate', ['$parse', function ($parse) {
    var directive = {
        restrict: 'A',
        require: ['ngModel'],
        link: link
    };
    return directive;

    function link(scope, element, attr, ctrls) {
        var ngModelController = ctrls[0];

        // Adjust timezone when date is selected from the datepicker
        ngModelController.$parsers.push(function (viewValue) {
            viewValue.setMinutes(viewValue.getMinutes() - viewValue.getTimezoneOffset());
            return viewValue.toISOString().substring(0, 10);
        });

        // Format 'yyyy-mm-dd' string for display
        ngModelController.$formatters.push(function (modelValue) {
            if (!modelValue) {
                return undefined;
            }
            var dt = new Date(modelValue);
            dt.setMinutes(dt.getMinutes() + dt.getTimezoneOffset());
            return dt;
        });
    }
}]);

The directive name should be added to the input element as follows:

<div class="col-md-6">
                    <label>Drawdown Ent. Date <span style="color: red;">*</span></label>
                    <input type="text" 
                           class="form-control" 
                           datepicker-local-date
                           datepicker-popup="yyyy-MM-dd" 
                           ng-model="bookloan.drawdown_ent_date" 
                           is-open="drawdown_ent_date.open" 
                          ng-click="drawdown_ent_date.open = true" 
                           datepicker-options="entDateOptions" 
                           date-disabled="disabled(date, mode)" 
                           close-text="Close" />
                </div>
            </div>
