Temporal shift

A temporal shift is a form of transport that is used to move beings across time. Temporal shifts are normally used in emergency cases because by using one, the traveller's power cells are greatly reduced.

The Cult of Skaro escaped the Battle of Canary Wharf in 2007 through an emergency temporal shift and arrived in New York City in 1930. (DW: Doomsday/Daleks in Manhattan) Likewise, Caan used an emergency temporal shift to escape from New York after the Doctor foiled the plans of the Cult of Skaro and led the rebellion of the Human-Daleks. When the three members were killed, Dalek Caan performed the shift. (DW: Evolution of the Daleks)

Caan ended up in the Time War, which was time locked, impossible to achieve. Regardless, Caan had succeeded, at the cost of his own sanity. (DW: The Stolen Earth)
