How to change date format in Admin panel viewing order or custumer listing

[fabiano_albernaz]

Sometimes date are handy coded

in Admin Panel ... Backoffice

the two listings of Orders and Customer are in YYYY mm dd - date format
independent from tha language you choose ...

change AdminOrders.php and AdminCustomers.php

l. 43 - 'date_add' => array('title' => $this->l('Date'), 'width' => 90, 'align' => 'right', 'type' => 'date', 'date' => true, 'filter_key' => 'a!date_add'),

+

l. 34 - 'birthday' => array('title' => $this->l('Birthday'), 'width' => 60, 'type' => 'date', 'birthday' => true),
l. 38 - 'date_add' => array('title' => $this->l('Registration Date'), 'width' => 60, 'type' => 'date', 'date' => true));

AND FINALLY AdminTab.php after elseif from price ... aprox ... l. 1120

elseif (isset($params['price']))
echo Tools::displayPrice($tr[$key], (isset($params['currency']) ? new Currency(intval($tr['id_currency'])) : $currency), false, false);

//NEW PART
elseif (isset($params['date']))
echo Tools::displayDate($tr[$key], $cookie->id_lang, true, '-');
elseif (isset($params['birthday']))
echo Tools::displayDate($tr[$key], $cookie->id_lang, false, '-');

...

ATENTION: true - full date with hours. false - no hours, '-' - separator


NOW I'M SEARCHING A WAY SO THE FILTERS WORKING PROPERLY WITH NEW DATE FORMAT
