Present a fight around that time (10)

I believe the answer is:

thereabout

'around that time' is the definition.
(thereabout means around a certain time)

'present a fight' is the wordplay.
'present' becomes 'there' (I've seen this in other clues).
'fight' becomes 'bout' (as in a bout in boxing).
'there'+'a'+'bout'='THEREABOUT'

I've seen this clue in The Guardian.
