aureport issues

Over the last few weeks, I have had 3 different machines start showing only the date of 12/31/1969 19:00:00 for the aureport logs. Seeing it on Fedora 6 and RHEL 5.5. I saw a few others posting on this same issue, but no answers. I am a newbie to linux/unix, and have exhausted all of my internal contacts too. I can't seem to find anything online for a fix anywhere (in English anyway) either. Any help is appreciated.
