Time anomaly relocation distributor
From Tardis Wiki, the free Doctor Who reference
The Time anomaly relocation distributor was a feature of the TARDIS that took effect when a potentially dangerous time anomaly was detected. By default it moved the TARDIS forward "an hour or two". In this sense, it served the same purpose temporally as the HADS did spatially.
This failsafe took effect when the Fifth Doctor's TARDIS was sent back in time by an ergostorm.
The name "Time Anomaly Relocation DIStributor" was a bit of a mouthful, but unfortunately it couldn't be shortened to its obvious acronym, "TARDIS", as that would be apt to cause confusion. (AUDIO: Aquitaine)
