Changing Filename date format to yyyy-mm-dd Issues

[wowbagger]

This works ok. But you should set up some sample files for testing on.
There are some details here on how to use it Rename Scripts

function lpad( val, pad ) {
  if (!pad) pad='';
  var rtn=val.toString();
  return (rtn.length<pad.length) ? (pad+rtn).slice(-pad.length) : val;
}

function OnGetNewName(getNewNameData)
{
	var year;
	var month;
	var day;
	var matched = false;
	var item = getNewNameData.item;
	//DD-MM-YYYY D-M-YY
	var reg = new RegExp('([0-1]?\\d)[-.]([0-3]?\\d)[-.]((?:19|20)?[0-9]{1,2})|((?:19|20)?[0-9]{1,2})[-.]([0-3]?\\d)[-.]([0-1]?\\d)');
	if(reg.test(item.name))
	{
    	DOpus.OutputString(item.name + " matched 1 DD-MM-YYYY or YYYY-MM-DD");
		day = item.name.replace(reg, "$1$6");
   		month = item.name.replace(reg, "$2$5");
   		year = item.name.replace(reg, "$3$4");
		matched = true;
    }

	if(!matched)
	{
		//DDMMYYYY
		var reg = new RegExp('([0-1]?\\d)([0-3]?\\d)((?:19|20)[0-9]{2})');
		var regexMatch = reg.exec(item.name);
	    if (regexMatch != null) {
			DOpus.OutputString(item.name + " matched 2 DDMMYYYY");
			day = regexMatch[1];
	   		month = regexMatch[2];
