Do we know when Doctor Strange takes place ? I don't know if this was discussed or announced, but here I go.

At a point in the trailer, Strange says that to become a skilled doctor he needed years of studying. Then the trailer cuts to him studying and sporting a new haircut and a sexy beard.

So, does the first part of the movie -when he's travelling around the world to find a cure for his hands- take place prior to all the super hero stuff and the rest of the movie is set in the present ?
