Re: Timeline of Nolan's trilogy.
Many dates contradict each other. I think there's no set time frame to be honest. It's almost like LOST, most questions were answered by the finale but there's still a few more that they never answered and kept vague. You could draw up your own conclusions. It's kind of the same vibe here.
The timeline stuff, where Bruce/Selinas lives go from here, what Blake becomes, where Gotham is headed...some things are left open and that's that.
For every fan who thinks there was 6 months to a year between BB/TDK, there's another who will think Batman was active for a few years. The dates are all over the place as far as im concerned, so it doesn't really matter.
"Lets make one thing very clear here - Nolan's films are as faithful an adaptation as there is. It pays homage to its source material, remains true to its characters and above all else places the story first and foremost." - jmc
