Hi,
To replace "Created date" by "Updated date", please following these steps:
1. Open file: root > components > com_edocman > view > common > documents_table.php
2. Find:
Code:
echo JHtml::_('date', $item->created_time, $config->date_format, null);
and replace by
Code:
echo JHtml::_('date', $item->modified_time, $config->date_format, null);
Thanks
Dam
