Black and white TV episode with horrible face in mirror? Solved!

[Trevor]

I saw this on TV in 1978 - I think it may have been called The Clock or something similar to that - a house's evil is tied to a clock and at a certain time, a ghostly face starts to form  in a mirror.

I was only 11 when I saw this and it freaked me out - does anyone know what episode of which series I'm talking about?

Old, very old. 

Thanks ~ someone on the INTK board at the IMDB solved it for me ~ it's an episode of the Dick Powell Theatre entitled The Clocks.
