I'm stealing nuts and pips for one (4,6)
I believe the answer is:
time signal
'pips for one' is the definition.
(makes pipping sounds for one o'clock)
'i'm stealing nuts' is the wordplay.
'nuts' indicates an anagram (nuts can mean crazy).
'im'+'stealing'='imstealing'
'imstealing' with letters rearranged gives 'TIME-SIGNAL'.
'and' acts as a link.
(Other definitions for time signal that I've seen before include "Regular announcement from Greenwich?" , "up-to-the minute sound" , "beeps, perhaps" , "Eg, Greenwich pips" , "Electronic indication of the correct hour" .)
