Resolved year places a conjecture's proof in the year it actually appeared. Wikipedia notes that "in papers posted to the arXiv repository in 2002 and 2003, Perelman presented his work proving the Poincare conjecture," nearly a century after Poincare first posed it. Browsing by resolved year shows how long a hard problem can remain open before it finally falls.
