Coffee time (7)

I believe the answer is:

instant

I believe this is a double definition.

'coffee' is the first definition.
(instant coffee)

'time?' is the second definition.
(I know that instant is a type of bit)

(Other definitions for instant that I've seen before include "Trice" , "Precise moment" , "Mo" , "Without delay - short time" , "Sudden; moment" .)

I've seen this clue in The Sun, The Everyman puzzle in The Observer and The Independent.
