I believe the answer is:

imprisoned

I'm a little stuck... Click here to teach me more about this clue!

'having time to spend in a cooler' is the definition.
I can't judge whether this definition defines the answer.

'situation' is the wordplay.
I cannot really see how this works, but
'situation' could be 'prison' (prison is a kind of situation) and 'prison' is found in the answer.
This explanation may well be incorrect...

Can you help me to learn more?

(Other definitions for imprisoned that I've seen before include "in jail" , "Put away" , "Locked up" , "behind bars" .)

I've seen this clue in The Globe and Mail.
