由于数据加载，需要暂停脚本以避免日期戳01/01/1970

Question

我有一个归档脚本现在可以正常工作，但是在备份时我确实从第一张单元格A2中得到了正确的日期，但在另外3张表格中，我在归档日期戳列中获得了01/01/1970片。所以我假设我需要暂停脚本以允许新页面从工作表名称加载A2中的日期。我在第33行添加了一个停顿，但现在我在所有工作表中都获得了01/01/70！我现在让它一夜之间运行，当我检查这个时，我有ll 4张01/0/1970，所以我假设延迟不够或在脚本中的错误位置，有人可以帮忙吗？

    function onOpen() { // This function adds a custom menu to the 
spreadsheet (Backup to archive) so you can run the script from there.
var ui = SpreadsheetApp.getUi();
    ui.createMenu('Backup')
    .addItem('Backup','dataBackup')
    .addToUi();
 }
 function nameOfSpreadsheet()
 {
   var s= SpreadsheetApp.getActive().getName().replace(/(\d{1,2}\.\d{1,2}\.\d{1,2}).*/,'$1');
 return s;
 }

  function dataBackup() {
  var inputSS = SpreadsheetApp.getActiveSpreadsheet();
  var archiveSS = 
  SpreadsheetApp.openById('146WU8RghfFqlCpCSX7n6kBAKOyxcpVKt14yhVfvYz-g');
  var user = Session.getActiveUser().getEmail();
  var sheetNames = ['AM trip', 'PM trip', 'Pool / Beach', 'Night Dive'];
  for (var i = 0; i < sheetNames.length; i++) {

    var inputSheet = inputSS.getSheetByName(sheetNames[i]);
    var archiveSheet = archiveSS.getSheetByName(sheetNames[i]);

    var date = inputSheet.getRange('A2').getValue(); // Changed to stop 
   inadvertent cell changes, also made text white so not seen.
    var data = 
  inputSheet.getRange('E7:U37').getValues().filter(function(row) { return 
  row[0] !== '' || row[1] !== ''});

    for (var x = 0; x < data.length; x++) {
        data[x].splice(0, 0, date);
    }
     var getDate = archiveSheet.getRange(archiveSheet.getLastRow(), 
   1).getValue();
    var maxRowLength = data.reduce(function(length, row) { return 
    Math.max(length, row.length); }, 0);
    var date = new Date(date); 
    var getDate = new Date(getDate);
    if (getDate.getDate() === "Loading Data...") {
    Utilities.sleep(10000);
     }
    if (getDate.getDate() != date.getDate() || getDate.getMonth() != 
  date.getMonth()) {     

        if (data.length != 0) {
            archiveSheet.insertRowsAfter(archiveSheet.getLastRow(), 
  data.length);
            archiveSheet.getRange(archiveSheet.getLastRow() + 1, 1, 
  data.length, maxRowLength).setValues(data);
        } else {
            archiveSheet.insertRowsAfter(archiveSheet.getLastRow(), 1);
            archiveSheet.getRange(archiveSheet.getLastRow() + 1, 1, 1, 
 2).setValues([[date, 'No Data']]);
        }
    }

  }
  }
