There was no aversion in my answer it was not my intention.
I profundly apologize. Sometimes the language is making confusion.
I should have ask you before the version you was running.
I didn't uploaded anything today.
When I say it was closed, I do not reffers to an existing topic. Your catch is good. I only say that I remember now it is working differently, so the issue cannot be raised anymore. (I only fix on V2.0)
I explain :
a helper is extending the native functionalities of the JDate. In version 1.5 it was in helpers/helper.php, and now it is in helpers/date.php
...and also, I access now with $date = JFactory::getDate() wich instanciate automatically the line you have mentioned.
The first thing I did before to answer you was to add you a point of Karma, so my intention was really to thanks you.
By the way, what is the JLoader for ?
JLoader::import( 'bloondatum' , JPATH_SITE_LEERLING . DS . 'models' );
Still learning...
