My server is returning me dates in UTC and I want to convert them to the timezone of the server (even if the customer browser is in a different timezone !)

Here is one example, my server is in Europe/Berlin.

var dateAsString = '2022-04-11T22:00:00.000Z'; // 2022-04-12 00:00:00 in Europe/Berlin
var utcDate = moment.utc(dateAsString);
console.log(utcDate.format());
var serverTzDate = utcDate.clone().tz('Europe/Berlin');
console.log(serverTzDate.format());
console.log(serverTzDate.format());

var test = moment.utc('2022-04-11T22:00:00.000Z').tz('Europe/Berlin').format();
console.log(test);

<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.29.2/moment.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/moment-timezone/0.5.34/moment-timezone-with-data-10-year-range.js"></script>

If my browser is in the Europe/Berlin timezone the output is correct:

2022-04-11T22:00:00Z
2022-04-12T00:00:00+02:00
2022-04-12T00:00:00+02:00

But if I change my timezone (for my example I took Pacific/Niue), then the result is totally wrong, I suppose moment is doing something with the timezone of the browser but how to avoid this ? Here is the output:

2022-04-11T09:00:00Z
2022-04-11T11:00:00+02:00
2022-04-11T11:00:00+02:00

I need to have the date in the timezone of the server and not in the timezone of the browser

With another timezone: Pacific/Kiritimati (-840)

2022-04-12T10:00:00Z // Wanted 2022-04-11T22:00:00Z (UTC Date as entered)
2022-04-12T12:00:00+02:00 // Wanted 2022-04-12T00:00:00Z (Converted in Europe/Berlin)
2022-04-12T12:00:00+02:00 // Wanted 2022-04-12T00:00:00Z (Converted in Europe/Berlin)
2022-04-12T12:00:00+02:00 // Wanted 2022-04-12T00:00:00Z (Converted in Europe/Berlin)

Again all the dates are wrong, moment seems not able to parse my date as an UTC date ? It apply the timezone offset of the browser even if I'm using the utc method
