Hi Lung,
That should be good. Here is what I did here:

[brian@bmicek ~]$ export HISTTIMEFORMAT="%d/%m/%y %T "

Then I did typed "history" and observed this:

 1000  18/07/11 21:00:05 export HISTTIMEFORMAT="%d/%m/%y %T "
 1001  18/07/11 21:00:06 ls
 1002  18/07/11 21:00:12 history

The change I made only applies to this one shell, but I think your command is good. Are you sure your shell is bash? To check, run a command like this:

[brian@bmicek ~]$ grep $USER /etc/passwd

and look for /bin/bash as the last colon delimited field.

After I run [brian@bmicek ~]$ grep $USER /etc/passwd
root:0:0:root:/root:/bin/bash

Very interesting! Can you run this command please?

[brian@bmicek ~]$  echo $HISTTIMEFORMAT
%d/%m/%y %T

also:

[brian@bmicek ~]$ bash --version
