I have completed my PhD 10 years ago, and back then I was not sure if it was ok with my home institution to have it in arxiv. I then realized it's fine and it would actually be good as my institution never cared to set up an open database of their own PhD theses. My question is: is there a way to post it on arxiv with the proper date, so that it shows on a search but it does not show among the most recent ones?

EDIT: given the popularity of the question, would it make sense to allow the ability to backdate ONLY PhD theses? It seems like my experience is a shared one, and I can't imagine anybody in her/his own mind lying on when she/he got her/his PhD.
