I just create a filter to convert my date to time. And I would call in the official filter "date" of AngularJS.

project.date_created_at and project.mel don't have the same format. So I need to create a custom filter for project.date_created_at.

HTML :

<span>{{ project.date_created_at | dateCustom }}</span>
<span>{{ project.mel | date:'dd/MM/yyyy' }}</span>

JS :

myApp.filter('dateCustom', function () {
    return function (input) {

        if(input != undefined) {
            var d = new Date(input);
            var time = d.getTime();
            // use official $filter('date') here ?
        }

    }
});

I would like to use this format :

date:'dd/MM/yyyy'

You can inject $filter as a dependency like you would do it for a controller, a service or a directive.

myApp.filter('myFilter',[ '$filter', function ($filter) {
    return function (input) {
      /**
         Do your stuff
      **/
      return $filter('date')(myDate,myFormat);
    }
}]);

On a side note, you should use angular.isDefined instead of != undefined.

See the documentation of $filter and of date for more details
