shieldDatePicker format not working

[danigrosu]

I am trying to use shieldDatePicker with a specific date format but the framework prints something like
Thu Nov 19 2018 00:00:00 GMT+0200 (GTB Standard Time) no matter the format I use (even if I let de default one) like:

<input id="picker" ></input>
 
<script type="text/javascript">
    $(function () {
        $("#picker").shieldDatePicker();
    });
</script>
