Time spillage

A time spillage was a temporal phenomenon which altered the flow of time. (TV: The Mark of the Rani) Alexhendri Lassiter defined time spillage as "quantum aberrations", a waste product caused by penetrating the Time Vortex. (PROSE: The Crystal Bucephalus) Osirians could absorb time spillage and use it to travel in time. (PROSE: The Sands of Time)

When the Rani visited Killingworth in the 19th century to gain the chemicals she needed on Miasimia Goria, the Sixth Doctor gained access to her TARDIS and tampered with the controls, making adjustments the navigational system and velocity regulator. When the Rani dematerialised, her ship accelerated out of control and time spillage caused her tyrannosaurus rex embyro to rapidly mature. (TV: The Mark of the Rani)

The Doctor's TARDIS materialised next to the Vipod Mor because it detected time spillage coming from the ship, caused by experiments with time. (AUDIO: Slipback)

Time spillage caused time shifts on a hotel suspended in the Vortex which had been exposed to time winds. When Jamie McCrimmon became ill from time spillage, the Second Doctor gave him a boiled sweet which made him feel better. (PROSE: Vortex of Fear)

The Crystal Bucephalus used dichronomide pentafiuorate to absorb time spillage and convert it into harmless radiation. (PROSE: The Crystal Bucephalus)

Ferran, in an attempt to kill the Eighth Doctor and Miranda Dawkins, decoupled the time engines of the Supremacy, throwing them out of phase and releasing time spillage which caused the engineers to rapidly age. (PROSE: Father Time)

The Tenth Doctor detected time spillage on a spacecraft transporting Pakafroon Wabster, which eventually caused a time loop. (COMIC: Interstellar Overdrive)

A fraxis pod which arrived at modern day Croydon released time spillage, causing some of the local plant life to evolve millions of years in a few seconds. (COMIC: Blooms of Doom!)
