DateTimePicker Localization/Translation for Formbuilder(which is included via Iframe)

[Orkun]

I have set the right Datepicker translation file "/wire/modules/Jquery/JqueryUI/i18n/jquery.ui.datepicker-de.js".

And change the code from:

/* German initialisation for the jQuery UI date picker plugin. */
/* Written by Milian Wolff (mail@milianw.de). */
jQuery(function($){

	$.datepicker.regional['de'] = {
		closeText: 'schließen',
		prevText: '<zurück',
		nextText: 'Vor>',
		currentText: 'heute',
		monthNames: ['Januar','Februar','März','April','Mai','Juni',
		'Juli','August','September','Oktober','November','Dezember'],
		monthNamesShort: ['Jan','Feb','Mär','Apr','Mai','Jun',
		'Jul','Aug','Sep','Okt','Nov','Dez'],
		dayNames: ['Sonntag','Montag','Dienstag','Mittwoch','Donnerstag','Freitag','Samstag'],
		dayNamesShort: ['So','Mo','Di','Mi','Do','Fr','Sa'],
		dayNamesMin: ['So','Mo','Di','Mi','Do','Fr','Sa'],
		weekHeader: 'KW',
		dateFormat: 'dd.mm.yy',
		firstDay: 1,
		isRTL: false,
		showMonthAfterYear: false,
		yearSuffix: ''};
		
	$.datepicker.setDefaults($.datepicker.regional['de']);
});

to:

/* German initialisation for the jQuery UI date picker plugin. */
/* Written by Milian Wolff (mail@milianw.de). */
jQuery(function($){

	$.datepicker.regional['de'] = {
		closeText: 'schließen',
		prevText: '<zurück',
		nextText: 'Vor>',
		currentText: 'heute',
		monthNames: ['Januar','Februar','März','April','Mai','Juni',
		'Juli','August','September','Oktober','November','Dezember'],
		monthNamesShort: ['Jan','Feb','Mär','Apr','Mai','Jun',
		'Jul','Aug','Sep','Okt','Nov','Dez'],
		dayNames: ['Sonntag','Montag','Dienstag','Mittwoch','Donnerstag','Freitag','Samstag'],
		dayNamesShort: ['So','Mo','Di','Mi','Do','Fr','Sa'],
		dayNamesMin: ['So','Mo','Di','Mi','Do','Fr','Sa'],
		weekHeader: 'KW',
		dateFormat: 'dd.mm.yy',
		firstDay: 1,
		isRTL: false,
		showMonthAfterYear: false,
		yearSuffix: ''};
		
	$.datepicker.setDefaults($.datepicker.regional['de']);

	$.timepicker.regional['de'] = {
        timeText: 'Uhrzeit',
        hourText: 'Stunde',
        minuteText: 'Minute',
        secondText: 'Sekunde',
        millisecText: 'Millisekunde',
        timezoneText: 'Zeitzone',
        currentText: 'jetzt',
        closeText: 'schliessen',
    };

    $.timepicker.setDefaults($.timepicker.regional['de']);
});

But it only affects the date and not the time. What I'm missing?
