About three minutes' fighting (6)

I believe the answer is:

around

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

'about' is the definition.
(I know that about can be written as around)

I don't understand the rest of the clue.

(Other definitions for around that I've seen before include "Present; approximately" , "On all sides or near" , "Close to" , "In the area of" , "About, here and there in circular way?" .)

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