Time's no good for holding in desire (8)
I believe the answer is:
yearning
'desire' is the definition.
(yearning is a kind of desire)
'time's no good for holding in' is the wordplay.
'time' becomes 'year' (I've seen this before**).
'no' becomes 'n' (common abbreviation).
'good for' becomes 'g' (I've seen this in other clues).
'holding' means one lot of letters goes inside another.
'n'+'g'='ng'
'ng' placed around 'in' is 'ning'.
'year'+'ning'='YEARNING'
(Other definitions for yearning that I've seen before include "Craving" , "Unfulfilled desire or need" , "Longing (for something)" , "Intense longing" , "Longing, pining" .)
