I'm using this function in a Google Apps Script:

function dateDiffYears() {

  var datas = [ [Date(2005, 7, 20), Date(2004, 2, 17)],

              [Date(2008, 9, 1),Date(2007, 5, 25)], 

              [Date(2010, 11, 2),Date(2010, 7, 28)], 

              [Date(2014, 0, 24),Date(2013, 1, 27)] ];



  for (var i= 0; i < datas.length; i++){

    var d1 = datas[i][0];

    var d2 = datas[i][1];

  Logger.log(d2  =  + d2 );

  Logger.log(d2 instanceof Date =  + (d2 instanceof Date) );

  Logger.log(d1  =  + d1 );

  Logger.log(d1 instanceof Date =  + (d1 instanceof Date) );

    var t2 = d2.getTime();

    var t1 = d1.getTime();

    Logger.log(d1 =  + t1);

    Logger.log(d2 =  + t2);

    var result =  parseInt( (t2-t1)/(24*3600*1000) );

    Logger.log(diff =  + result);

       }

}

As I can remember, this function worked in the past. But now, when I run it, I got this error message: TypeError: Cannot find function getTime in object Sun Jan 26 2014 10:23:10 GMT-0200 (BRST). (line 22, (line 22 is var t2 = d2.getTime();). I don't understand this error. What is wrong with the Date(yyyy, mm, dd) formate? And why the error message is talking about today date (ex:Sun Jan 26 2014 10:23:10 GMT-0200 (BRST)) since I'm not using New Date()?

How to fix it?
