While procrastinating over mathematical papers on Arxiv, I came across odd dates of the papers.

That is,

Ricci flow with surgery on three-manifolds, Grisha Perelman, February 1, 2008

The entropy formula for the Ricci flow and its geometric applications, Grisha Perelman, February 1, 2008

Who made the edit to the dates? Or, is there a different administrative task being done by moderators from time to time?

Thanks. I will delete this post if it is seriously off-topic.

The paper was uploaded as TeX to the ArXiV, and did not specify a date. Therefore the date appearing (Feb 1, 2008) is when the source was converted to PDF (or PS or whatever format you are viewing).

If you download the source and compile it yourself, you should see today's date.

    @Rasmus: yes, the article document class just provides \today as a default. In my long illustrious publishing career, the editor has always (twice) provided all the dates for me.2011-06-10
