Question:
I seem to remember (most vaguely)a unit of time called a "Jiffy", or "Jiffi", or the like. This is not a joke. My memory thinks it was supposedly the time it took light to travel one centimeter in a vacuum! I can find no reference anywhere. Any foundation here? Also, I recall some wag colleagues at Lawrence Radiation Laboratory in the early 1960s labeling a nanosecond scale as "Light Feet" - works out very close!

Fred,

When people tell you, "They will be there in a 'jiffi' or a 'jif'", they are exaggerating, unless of course they can move at the speed of light.

A 'jiffi' or 'jiffy' is the time it takes LIGHT to traverse the distance of 1 centimeter (33.3 pico seconds = 0.000,000,000,033,300 seconds). 1 light - cm is pretty quick !!
