How to extend script on next column?

How should I modify the script, in a way that it would work also in another column, eg. by putting data in A:A date will be printed in B:B and also in C:C

function onEdit() {   var sheetName = "MySheet";   var s = SpreadsheetApp.getActiveSheet();   if (s.getName() !== sheetName) return;   var r = s.getActiveCell();   if( r.getColumn() != 2 ) { //checks the column     var row = r.getRow();     var time = new Date();     time = Utilities.formatDate(time, "GMT+05:30", "dd-MM-yyyy, hh:mm a");     SpreadsheetApp.getActiveSheet().getRange('B' + row.toString()).setValue(time);   };  };
