Using Power automate to run a script which works fine but I need to run it in UTC time and date format (Singapore)

using a script I found here

function main(workbook: ExcelScript.Workbook) {
  let worksheet = workbook.getWorksheet("Sheet1");

  // Get the cells at A1 and B1.
  let dateRange = worksheet.getRange("P17");
  let timeRange = worksheet.getRange("Q17");

  let date = new Date(Date.now() + (3600 * 1000 * 0));

  dateRange.setValue(date.toLocaleDateString());

  timeRange.setValue(date.toLocaleTimeString());

}

I need to change it away from local time as that is in American format plus 3 hours Perth Vs Sydney

thank you
