Looks like this is the final word regarding how the timelines work.

So, everything in Flashpoint is PRe-Flashpoint timeline or Flashpoint timeline except for the post-credits sequence.
Also, just finished Batman vs Robin. This may be loose, but I think the film should be moved to March 2014 rather than January. Early in the movie, Bruce says "After all these months together. All I taught you. You revert to the assassin your grandfather wanted you to be." Right now, where we have it is two months after Son of Batman. However, a little later on it's revealed Bruce and Samantha have been dating for 3 months.
We first get confirmation that the Court of Owls is tracking Damian in "Nightwing and Robin", which happens during Throne of Atlantis (Nov. 2013), and while we learn in BvR that Samantha was unaware Bruce and Batman were one and the same, it makes sense, to me at least, that the Court of Owls would start work on both plans around the same time. With the potential of up to 14 days between the two JL movies, and no mention of Samantha in any of the first 3 films, I'd say her involvement with Bruce likely started shortly after those films (most likely December) making the three-month mark in March.
Something else that I noticed, when the Court of Owls has Bruce drugged Batwoman is in his vision.

I haven't watched all of bad Blood yet, but the intro scene seems to imply she's a relatively new member of the Bat-Family. "Dressing up like a bat doesn't make you a hero, it makes you a target. And using guns make you like one of them." so are we sure that the film takes place after BvR? I see that the reasoning in the first post states it's 6 months later, but doesn't mention if that was something specifically said in the film or just estimated.
