///What year is The Mysterious Planet set in?

User:SOTO/Forum Archive/The Panopticon/@comment-28743561-20180307013354 I feel like I'm going insane. Everywhere on this wiki it is said that The Mysterious Planet (and Iceworld) are set circa the year 2,000,000 (2 million).

However, the Doctor very clearly say it is "Oh, a long time after [Peri's] period. Er, two billion years or more." (Video)

Is there something wrong with my ears? I tried fixing this, but my edits were undone.
