LatestNews+ Date is an enhance version of the standard Joomla latestnews module with an additional thumbnail, date and time features for each news. You can display the date or the time on the article published in front of the article item title. Additionally, you also can display the thumbnail of the first article image and introtext of latest article item.
In the file mod_latestnewsplusdate/tpml/default.php I changed line 132 (the one under case 1:) to the following:
echo strftime("%d %B %Y", strtotime(date($item->created)));
This worked very well. Of course you can make similar changes elsewhere in the file. Note that I'm not a PHP guru so there might be cleaner ways to achieve the same thing but this works for me.
