Description:
------------
The function GetDate interprets the both timestamps as October 17th, 2004. 

The timestamps are: 1097895600  and 1097978400



Reproduce code:
---------------
$tbDataInicial = '2004-10-01';
$tbDataFinal_temp = '2004-10-31';

while ($sDataLoop != $tbDataFinal_temp)
{
  if ($sDataLoop == "")
  {$sDataLoop=$tbDataInicial;}	   

  //Add one more day
  $nTimeStamp=strtotime($sDataLoop);	  
  $sDataLoop = getdate($nTimeStamp);
  $sDataLoop=date("Y-m-d",mktime(0,0,0,$sDataLoop['mon'],$sDataLoop['mday']+1,$sDataLoop['year']));
}

Expected result:
----------------
The while should go through the parameters $tbDataInicial and $tbDataFinal that represents the begin and end dates respectively. 


Actual result:
--------------
This generates and infinite loop since $sDataLoop get stucked on the day October 17th, 2004.
