Operation Time is the 6th produced, and the 8th broadcast, episode of the British television series Captain Scarlet and the Mysterons.
In an exclusive London clinic, General J. F. Tiempo - Commander of the Western Regional World Defence - is due to undergo a brain operation, under the supervision of Dr. Theodore Magnus, a pioneering surgeon who has developed a revolutionary piece of apparatus known as the Cerebral Pulsator...
Night falls, and tragedy strikes...as, driving home, Magnus dies when his car is forced off the road by Captain Black. The now-Mysteronised Magnus returns to the clinic, with one purpose only - to kill Time!
