Watering can create inconvenience, when getting time in for golf (10)
I believe the answer is:
irrigation
'watering' is the definition.
(I've seen this before)
'create inconvenience when getting time in for golf' is the wordplay.
I cannot quite understand how this works, but
'when' could be 'on' (I've seen this in other clues) and 'on' is found in the answer.
'time' could be 't' (abbreviation) and 't' is found within the answer.
'golf' could be 'g' (phonetic alphabet: alpha, bravo, charlie etc.) and 'g' is found in the answer.
This may be the basis of clue (or it may be nonsense).
'can' acts as a link.
(Other definitions for irrigation that I've seen before include "an answer to all clues, initially" , "water distribution" , "The supply of water to crops" , "watering process" .)
