How long does an academic candidate have on the market?

From the humanities, a rather terrifying notice for faculty candidates from Brian Leiter, via Marginal Revolution:

Philosopher Daniel Weiskopf (Georgia State) calls my attention to a quite startling ad for a job in English at Colorado State University, which requires that applicants have earned the PhD since 2010!  As the linked post notes, given the state of the humanities job market, everyone knows there are lots of very good candidates with PhDs from 2009, 2008 and, horrors, even 2007 who still haven't found suitable appontments.  This ad promises to consign them to the discard pile without even looking at them.  Hopefully we won't see such ads in philosophy.

Haven't seen such ads in chemistry, but I am sure that readers will point them out.

UPDATE: Astute commenter Anon100220120537p notes that the ad has been changed after the outcry. From Inside Higher Ed:

The revised posting does not have the previous requirement, and instead specifies that the job is “entry-level.” “In light of the response to our initial ad, we examined how we could better describe the parameters of our search. We posted an updated position announcement that informs applicants that the position is entry-level and removes the restriction on date of degree. We invite all qualified and interested applicants to apply for the position," said Louann Reid, chair of English at Colorado State, in an e-mail to Inside Higher Ed.

In other words, there now, we won't be honest anymore.
