Based on the football results seen in the paper, Man City vs. Ajax 2-2 and Schalke vs. Arsenal 2-2, the episode is taking place November 7 2012.
The scene that takes place in Hamburg shows something, that is apparently a jury in a murder trial. There is no such thing as juries in German jurisdiction.
In the opening scene, the standing monk mutters a Tibetan greeting to the others. He seems to mispronounce it as "Tashi Dalek." Writer and co-creator Steven Moffat is show-runner and writer for Doctor Who (2005), in which the Daleks are a race of alien villains and the Doctor's main nemesis.
A very short self-contained episode, that served as both a teaser for the next series, and could be enjoyed as an extended deleted scene from the start of the season proper.
