Time slip

Time slip relates to the Doctor Who multimedia franchise. It was used as a plot device in the four-part 1979 series "City of Death", starring Tom Baker as the Fourth Doctor.

A time slip is a phenomenon found in temporal mechanics in which a specified period of time repeats itself as if it were a skipping record. Time slips usually occur near an area where the space/time continuum has been adversely affected, usually caused by scientific experimentation.
