^^I don't know what that is, but it's definitely not the WTC. Besides the Doctor stated that they were in 2012.
Here's roughly how Amy's timeline should work:
1996: Meets the Doctor for the first time (14 years prior to her wedding, confirmed to be in 2010)
2008: The whole Atraxi thing (two years before her wedding)
2010: The wedding (confirmed on screen)
2011: The Doctor fakes his death (confirmed on screen) and Amy and Rory stop travelling in the TARDIS (conjecture, assumes it's still the same year).
2013: The Doctor visits the Ponds on Christmas (Amy says it's been two years since they've seen him).
2014: Pond Life (conjecture, it takes place from April to August, though no year is given) and Asylum of the Daleks (also conjecture, assuming not much time has past since Pond Life).
2015: Dinosaurs on a Spaceship (Conjecture based on Amy saying it's been ten months since Asylum. Assuming Asylum is August 14, this would June 15).
2015-2016: The Power of Three (Conjecture based on episode being set from July of one unspecified year to July the next).
And then for some reason The Angels Take Manhattan is 2012.
