Time is pressing (7)
I believe the answer is:
instant
This clue is a double definition.
'time' is the first definition.
(I know that instant is a type of bit)
'is pressing' is the second definition.

(Other definitions for instant that I've seen before include "The blink of an eye" , "Short time; immediate" , "Occurring with no delay" , "A second - coffee, maybe" , "Mo" .)
