The 1970s was a temporally complicated decade in history.

Temporal complications

Due to numerous visits by the Doctor's faulty TARDIS, the 1970s merged with the succeeding 1980s, resulting in the placing of events becoming distorted and disputed. In light of this, the Accord, foreseeing a "great war spreading through time", reinforced the vulnerable decades by altering the DNA of every single person who lived within them on a temporal level so that they subconsciously realised that there were inconsistencies with history. In response to the temporal discrepancies, a dating protocol was established by the United Nations on 1 January 1990, (PROSE: The Enfolded Time) which would be used as a reference by the Unified Intelligence Taskforce. (TV: The Day of the Doctor)

Celestial Intervention Agency Coordinator Narvin described the 1970s as "unruly". (AUDIO: The Death of Hope) The Fourth Doctor once described being in the late 1970s as much the same as being in the realm of the dead. (AUDIO: Suburban Hell)
