[ale] Kubuntu won't sudo

[briarpatchkid at bellsouth.net (Jim Philips)]

I installed Kubuntu over the weekend and am generally impressed. However, I 
have one problem: It won't keep the right time, even after I set the time 
zone to Eastern Standard. It was showing something 4 hours ahead. No problem. 
I got in and set it to the correct time. But now when I try to sudo, it says:

sudo: timestamp too far in the future: Aug 13 22:43:44 2006

This is approximately the time it was showing when I corrected the setting.
