Problem to filter on date

Hi.

I am french , I’ve create a script who count how many tweet / like exists on posts related to one post.

For exemple , I have a single post which is Microsoft , a simple slide about the company and I have some other type of post called “news”.
I Count the like / tweet for each news and I create a global count on the post Microsoft.

This part of the script works very well, but when I want to had a filter on the date of publication, it’s doesn’t work. That I try; is to select only the “news” I have write since 30 days but my function return only the post I have write since 30 days.

Here is my script, and you can see the result on this URL : http://www.frenchstartups.com/script-total.php
Do you have an idea how to make this work ?
Thanks a lot ,
Regards , Florian
