They talked in the nemeton in about September 2011, the 9th month of 2011.

Suppose Claudia died in the beginning of 2004 (say like Jan.17 2004), then the whole 2004 counts as the first year, and 2005 the second, 2006 the third, 2007 the fourth, 2008 the fifth, 2009 the sixth, 2010 the seventh and 2011 the eighth. Nothing wrong.

You may argue that technically it would be like died 7 years, 9 months ago...but it's very reasonable if Sheriff simply rounds that time to a simple "8 years ago". It would be kind of awkward and unnecessary to say like "She died 7 years, 7 months ago" in that scene, and the year 2011 has also passed for over two thirds.

So IMHO the "discrepancy" just offers a window to see more precisely around when Claudia died, and produces no contradiction at all, unless the show will say or has said (then I'd apologize for my carelessness) that Claudia didn't die in that winter/spring or has talked about the years' issue earlier.
