last visited always 10 days old?

Hi, I’d really appreciate it if you could help me out here.
I’d like to know how to set it up, so that when I log onto latest post I will only see the latest post from yesturday or even two days ago. At the moment when I leave the site and come back on again I have to wait for all the post that are new and old. Then I’m finding that I have to change the latest posts back to yesturday again. Can it just stay on yesturday permanently some how.

Thanks..[suave2]
