I just stuck the episode on. Watching it right now. In the first 10 seconds the Doctor says that they're in 2012 and Rose says that she would be 26 years old.
Yep. And in the first ten seconds of "Aliens of London," the Doctor was convinced he'd landed Rose in 2005, 12 hours after they dematerialized at the end of "Rose." Then he looked around and realized he'd parked in the wrong year.
