Hi
I have some problems with the dates of creation and modification. when I create a new ad, the dates are the same, right here. The problem comes when I change an ad. I am observing that the date of creation and modification is the same.
For example:

New ad:
date_created 2014/02/10
date_modified 2014/02/10

updating ad:
date_created 2014/02/12
date_modified 2014/02/12
Why is the created date 2014/02/12?? should be 2014/02/10

Anyone know what is happening?

I am modifying an ad in frondnend and backend and In this case it works fine, however, it seems that as if the ads themselves were updated. Example, I have this ad: ad_created :2014-02-23 22:48:35, ad_modified: 2014-02-23 22:48:35, publication_date: 2014-02-10 19:36:01. I don't understand what is happening.
I use adsmanager 2.9.7. The web is revistautil.com
Is more likely that the problem is in the frontend, the moderator only modifies the ad one time in the backend, the rest of times are the users that modify the ad in frondend.

Thanks you.
