Create a new Date for any specific timezone

I am using Google Apps Script to check and re-format date data from some Google Sheets. But the problem is the result shows the times for the user who run the code. I want to show the date for any specific time zone. How is it possible?

Suppose, my input is checkDate('14/5/2022'); and it returns the date
object for that time zone instead of my time zone.

Here is my code:

/**
 * This will return a JS Date object with a valid date input.
 * Unless this will return a false status
 */
function checkDate(input) {
  // const timeZone = SpreadsheetApp.getActive().getSpreadsheetTimeZone();
  if (input instanceof Date && !isNaN(input)) {
    // will execute if a valid date
    return input;
    
  } else {
    // If not a valid date
    const splitter = input.indexOf('/') === -1 ? '-' : '/';
    const dateArr = input.split(splitter);

    if(dateArr.length === 3) {
      const year = dateArr[2].length === 2 ? '20' + dateArr[2] : dateArr[2];
      const NewTime = new Date(Date.UTC(year, dateArr[1]-1, dateArr[0], 0, 0, 0));

      return NewTime;
    } else {
      return false;
    }
  }
}

console.log(checkDate(new Date()));
console.log(checkDate('14/5/2022'));

Expected input
checkDate('14/5/2022') and timeZone = 'GMT+1;

Expected Output
2022-05-14T00:00:00.000 french time. Not the UTC time.

Is it possible?
