Ok, add a "bash -i" and now is working well:

   #+BEGIN_SRC sh :session :results output
     grep bash ~/.emacs
     echo $SHELL
     echo $HOME
     alias | wc
     env | grep HISTTIMEFORMAT
     echo $BASH_VERSION
     shopt -s histappend
     set -o | grep history
     history | wc
     alias dia
     alias hh
     hh | tail
     history -a
   #+END_SRC

   #+RESULTS:
   #+begin_example
   (setq org-babel-sh-command "bash -i")
   /bin/bash
   /home/osiris
       534    3236   29894
   HISTTIMEFORMAT=%Y-%m-%d %H:%M
   4.2.37(1)-release
   history          on
      8275   44194  338107
   alias dia='date +%Y-%m-%d'
   alias hh='history | egrep $(dia)  | cut -c 19- | sort -u'
   17:10 set -o | grep history
   17:10 shopt -s histappend
   17:10 ssh sugar-mant
   17:10 sudo chown osiris.osiris config -R
   17:10 sudo chown osiris.osiris .* -R
   17:10 sudo chown osiris.osiris /var/run/screen/S-osiris
   17:10 sudo chown osiris.osiris /var/run/screen/S-osiris.*
   17:10 sudo -s
  #+end_example

Sometimes I forget to start clock in a task,
then I use the history to know the timestamp
:-P
