2001

The major alien threat of 2001 was that of a highly advanced breed of Cybermen. They invaded the Earth en masse, but were defeated by the Doctor and Destrii. (DWM: The Flood)

However the episode in question, Dalek (TV story) makes no reference to a specific date, and therefore a real life 2001 date can't be said to exist in the DWU.
