I don't even look at DIS time anymore! I have been around here for several years and I think the clock has been correct for about 2 hours, somewhere around 2 years ago. Not sure why but it is something they just can't fix.
Oh, sorry-- that just made me laugh! I have been waiting for them to fix it for several years now!
It is my understanding that the clock issue is something our Webmasters don't have control over. It is the function of something/one else? So I have given up and I just don't look at the time on posts, unless I want to just see how long has occured between posts.
