No time for getting tied up in pastime (7)
I believe the answer is:
angling
'pastime' is the definition.
(I know that angling is a type of Fishing)
'no time for getting tied up in' is the wordplay.
I cannot quite understand how this works, but
'no' could be 'n' (common abbreviation y/n) and 'n' is located in the answer.
'in' is found in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for angling that I've seen before include "Pursuit with hook, line and sinker?" , "riverside activity?" , "Walton practised it" , "Fishing with hook and line" , "seeking compliments, perhaps?" .)
