There's no hurry to get trousers for the prisoners (4,2,4)

'there's no hurry to' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.

'trousers for the prisoners' is the wordplay.
'trousers' becomes 'bags' (informal term for trousers, Oxford bags).
'for' says to put letters next to each other.
'the prisoners' becomes 'oftime' (I can't explain this - if you can you should believe this answer much more).
'bags'+'oftime'='BAGS OF TIME'

'get' acts as a link.

Can you help me to learn more?
