'no matter' is the definition.
Both the answer and definition are adverbs. Maybe there's an association between them I don't understand?

'it may net a gross' is the wordplay.
'gross' indicates anagramming the letters.
'it'+'may'+'net'+'a'='itmayneta'
'itmayneta' is an anagram of 'AT ANY TIME'.

'when' is the link.
