Behind the scenes
22.09.72.2540 is given as the time the Earth cargo ship C982 jumps into hyperspace at the beginning of the television story Frontier in Space and the Doctor tells Jo Grant that they are in the 26th century. 2540 is explicitly cited as the year in the novelisation and the novel Shadowmind. The telelvision story Planet of the Daleks follows some time close to this point.
The novel Just War indicates that 25th century dates given in previous books for Bernice Summerfield's life were actually part of one of the other calendar systems in use in the Mutter's Spiral of her time. In another system, she was born in 2422. (PROSE: Falls the Shadow)
