如何更改cakephp中的默认日期格式？

I am using cakephp 2.5.x.

I have the following code in my controller;

$Dates = $this->Model->find('all');          
echo json_encode($Dates);

$Dates contain some dates with the default format being YYYY-mm-dd. How can I change it such that the format becomes dd-mm-YYYY?

$original_date = explode('/',$Dates);
$day= $original_date[0]; // 2014
$month = $original_date[1]; // 07
$year=  $original_date[2]; // 21
$date = $day.'/'.$month.'/'.$year;
echo $date;

$Date= $this->Date->find('all',array('fields'=>array('Date.created')));

foreach ($Date as $key => $value) {
   $date['date'] = date('d-m-Y',strtotime($value['Date']['created']));
}

echo "<pre>";
print_r($date);

I have made a small demo in CakePHP and It works fine. I have written it in my controller. You should try it.

Output :

Array ( [date] => 30-09-2014 )

You can set your date format as per you requirement.

// You can change date format Using TimeHelper like

echo $this->Time->format('2011-08-22', '%d %m, %Y');

Output

22-08-2011
