[sudo-users] Disabling timestamp message on HP-UX

[Powell_Stuart]

I recently installed sudo 1.6.9p8 on two new HP-UX 11i V3 integrity
systems.  I haven't made many modifications to the sudoers files.  There
are only three users configured so far and they are all in the root
group with full access to everything.  Whenever I enter a command via
sudo I receive the message detailing the last successful login on the
system and the last authentication failure on the system.  Similar to
below:
Last successful login:       Tue Aug 26 08:53:35 EDT 2008
pthspowell.aetinc.net 
 
Last authentication failure: Wed Jul 30 11:46:07 EDT 2008
pthspowell.aetinc.net
This text is distracting when troubleshooting a problem.  Any
suggestions on eliminating the prompts?  

Below is the sudoers file in use:
$ sudo cat /etc/sudoers
Last successful login:       Tue Aug 26 14:00:02 EDT 2008
th9kpux.aetinc.net  
Last authentication failure: Tue Jun 17 20:17:49 EDT 2008 /dev/console
