问当单元格更新时，我如何添加重新设置的计数计时器？

EN

function onEdit(e) {
  if (!e) {
    throw new Error('Please do not run the script in the script editor window. It runs automatically when you hand edit the spreadsheet.');
  }
  const columnToWatch = 3; // column C = 3
  const timerCellOffset = 10 - columnToWatch; // column J = 10
  const timerFormula = '=now() - value("<<NOW>>")';
  const sheet = e.range.getSheet();
  if (e.range.columnStart !== columnToWatch
    || e.range.rowStart <= sheet.getFrozenRows()
    || !sheet.getName().match(/^(Dispatch Main|Sheet1|Sheet2|Sheet3)$/i)) {
    return;
  }
  const nowString = Utilities.formatDate(new Date(), e.source.getSpreadsheetTimeZone(), 'yyyy-MM-dd HH:mm:ss');
  const formula = e.value
    ? timerFormula.replace('<<NOW>>', nowString)
    : '';
  e.range
    .offset(0, timerCellOffset, 1, 1)
    .setFormula(formula)
    .setNumberFormat('m:ss');
}
