The DNG converter does not actually "convert" your raw images, but rather creates a DNG additional copy of that image. It uses the computer date as a source for the time of the creation of that file. However, the original date and time will still be part of the metadata for each file.
The problem is that the file date is changed by dng converter, when I want to rename the file with DNG as a parameter of the date of creation of the photo, the renamer is in the name of the date of creation dng, it can not go to my ranking of my photos .... I do batch converting all my pictures are dated the same date

Well, this is the way it works. C'est la vie!
Perhaps there's a way of achieving what you want through scripting, by writing a script that can read into the metadata of the file, where the date taken is preserved.
You may want to post in the Bridge Scripting or Photoshop Scripting forum.

There are three potential dates with a digital capture, the Date/Time the file was created, the date/time the file was modified and the EXIF metadata Date/Time Original which is recorded by the camera at the moment of exposure. It is this final Date/Time that you would want to use in a name. Any time you create a new file–which is what DNG Converter is designed to do, you'll get a new date/time of that file's creation. That's not something the DNG Converter can change. If you take the DNG into ACR/Lightroom and modify the settings, you'll get a new date/time of the modification. However, the EXIF metadata will still correctly indicate the moment the capture was created in the EXIF Date Time Original tag.
So, what are you using to rename the files? If you are using Bridge to rename the file, the Date Time option when set to Date Created should be using the EXIF Date Time Original tag as the source of the date/time. Other apps should also be able to be set to use the EXIF Date Time Original tag.
You can use exiftool utility to set the date of dng file according to exif - something like
exiftool "-DateTimeOriginal>FileModifyDate" <filename.dng>
or for all files
exiftool "-DateTimeOriginal>FileModifyDate" *.dng
However, when you edit a dng with ACR, date will be updated again - unless ...
Can you rename the file before you do the DNG conversion?
