getDateObject doesn't recognize configured date format #980

At the moment the date is parsed like documented here: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/Date
But the "normal user" cannot know how this works internally. They just know their local date formats. var momentDate = moment('04.03.2022', 'DD.MM.YYYY');The problem is, that the same blockly / javascript would work differently when the system configuration changes. |

"The problem is, that the same blockly / javascript would work differently when the system configuration changes." In fact the same error still exists. I have now also switched to momentjs() in combination with the “moment-parseformat” plugin. The problem that the same Blockly/Javascript would work differently if the system configuration changes does not exist either... It would still be good if the functions could be corrected. Here is a short example of the problem and a possible alternative solution const moment = require('moment');
const parseFormat = require('moment-parseformat');
const targetFormat = 'DD.MM.YY';
moment.locale('de-DE'); //aus den 0_userdata locals oder aus dem System
for (let i=1; i<33; i++) {
//mal alle Tage über den gesamten Monat zusammenbauen
let Tag: string = '';
if (i < 10) {
// 0 davor, sonst gibts ne falsche Prüfung
Tag = '0' + String(i) + '.11.2023 00:00'; // moment-parseformat findet das Format zur Prüfung auch mit Uhrzeit
}
else {
Tag = String(i) + '.11.2023'; // oder ohne Uhrzeit --> oder völlig anders
}
// 31.11.2023 dürfte es nicht geben (also isValid = false) und dann kommt der Käse
if (i==32) {
Tag = 'Käse'; // um zu überprüfen ob 'Käse' auch als Datum validiert wird!!!
}
var pformat = parseFormat(Tag);
console.log(pformat);
// JS-Methode - nur zum Vergleich --> wird nicht sauber arbeiten!!!
console.log('Date.parse --> Ist das Datum ' + Tag + ' valid?: ' + !isNaN(Date.parse(Tag)));
// Erkennt das Datum
console.log('moments.js --> Ist das Datum ' + Tag + ' valid?: ' + moment(Tag, pformat, true).isValid());
if (moment(Tag, pformat, true).isValid()) { //Sting ist Datum in diesem Format
let DatumZeit = moment(Tag, pformat).unix(); // Umwandlung in Unix Time-Stamp
console.log('Umwandlung in Unix-Timestamp: ' + DatumZeit);
console.log('Formatierung über JS in Zielformat: ' + formatDate(DatumZeit, targetFormat));
}
else { // der String wird ausgegeben
console.log(i + ' x ' + Tag);
}
