如何在一天中的特定时间锁定Google工作表

function lockSheetAtSpecificTime() {
  var lockTime = "17:00:00"; // 设置要锁定的特定时间
  var sheetName = "Sheet1"; // 设置要锁定的工作表名称
  
  var lockDate = new Date();
  lockDate.setHours(lockTime.split(":")[0]);
  lockDate.setMinutes(lockTime.split(":")[1]);
  lockDate.setSeconds(lockTime.split(":")[2]);
  
  var sheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName(sheetName);
  var range = sheet.getDataRange();
  
  if (new Date() >= lockDate) {
    range.protect().setDescription("Locked at " + lockTime);
  } else {
    Utilities.sleep(lockDate.getTime() - new Date().getTime());
    range.protect().setDescription("Locked at " + lockTime);
  }
}
