Thanks for the hint, I had forgotten about apt-cache policy.
I finally understood, why the update was on the run:
tzdata:
   Installé : 2013d-0wheezy1
   Candidat : 2013d-1
  Table de version :
      2013d-1 0
         500 http://ftp2.fr.debian.org/debian/ testing/main amd64
Packages
  *** 2013d-0wheezy1 0
         500 http://ftp2.fr.debian.org/debian/ stable-updates/main 
amd64
Packages
         100 /var/lib/dpkg/status
      2013c-0wheezy1 0
         900 http://ftp2.fr.debian.org/debian/ stable/main amd64
Packages
Version 2013d-0wheezy1 had the same priority as testing one so 
testing
was installed because more recent.
Now, I wonder why I have 3 versions of that package listed when I 
only
have 2 sources enabled? Could it be because of stable, 
stable/updates
and stable-updates repositories? ( I am not used to stable, so I do 
not
have the "updates" repos usually )
And also why I have a wheezy version with a priority of 500... I can
not even find the 2013d-0wheezy1 in debian packages...
