Sam Forstman is an old man who lives with his granddaughter Marnie Kirk and her husband Doug. Sam lives a simple life and doesn't sleep much anymore. He's usually up at all hours tinkering on his grandfather clock, something that worries Marnie as his attention to the timepiece verges on the obsessive. The reason for that however is quite simple: he is convinced that should the clock ever stop, he will die. Written by garykmcd

Did You Know?


William Froug had Richard De Roy rewrite the George Clayton Johnson teleplay "Tick of Time" before it was aired as The Twilight Zone: Ninety Years Without Slumbering (1963). Johnson was displeased with this and ultimately never reconciled with Froug, and never contributed to The Twilight Zone (1959) again. See more »


We see the spirit leave Forstmann's body while he is asleep and walk to the foot of his bed. The spirit is a "see-through" image of him but the real body has "see-through" feet under the covers when seen in the side view. See more »


Narrator: [Opening Narration] Each man measures his time; some with hope, some with joy, some with fear. But Sam Forstmann measures his allotted time with a grandfather's clock, a unique mechanism whose pendulum swings between life and death, a very special clock that keeps a special kind of time - in the Twilight Zone.

Couldn't help feeling for the silly old fool.
2 December 2013 | by (Ireland) – See all my reviews

A whimsical story about a gentle, eccentric old man with a peculiar obsession with a grandfather clock. Best taken as an allegory not to let superstition or the past stand in the way of the present. Any supernatural element here might be taken as though merely psychological. Besides that Ed Wynn is larger-than-life enough, in a gentle way, to make the viewer see past the silliness of the tie-in with the Victorian clock song of the title. The story would be better without making that direct association.

Thanks to Ed Wynn (Mad Hatter's voice in Disney's 'Alice In Wonderland', as well as having acted Serling's own writing in 'Requiem For A Heavyweight', and in TZ 'One For The Angels') this becomes engaging on a human level.
