Pips possibly from fresh limes in a GT (4,6)
I believe the answer is:
time signal
'pips possibly' is the definition.
I can't tell whether this defines the answer.
'fresh limes in a gt' is the wordplay.
'fresh' is an anagram indicator (a fresh re-ordering of the letters).
'limes'+'in'+'a'+'gt'='limesinagt'
'limesinagt' with letters rearranged gives 'TIME-SIGNAL'.
'from' acts as a link.
Can you help me to learn more?
(Other definitions for time signal that I've seen before include "Eg, Greenwich pips" , "Regular announcement from Greenwich?" , "up-to-the minute sound" , "beeps, perhaps" , "eg Six pips" .)
