Time distortion

Time distortion referred to disturbances in space-time, including those caused by anachronisms.

Cyber-Technology could detect the Doctor's TARDIS by registering the time distortion it created. (DW: Attack of the Cybermen) It is possible that all time vessels generated time distortion, as the Sixth Doctor was able to track the Rani based on this. (DW: The Mark of the Rani) The Third Doctor thought of the Rani as an expert in time distortion. (DW: Dimensions in Time)

Time distortion was present in the Humanian Era, the Sensorian Era, and the Sumaran Era, caused when the Eighth Doctor rescued Charley Pollard from the R101. (BFA: Neverland)
