Had in mind poor time (5)
I believe the answer is:
meant
'had in mind' is the definition.
('mean' can be a synonym of 'have in mind')
'poor time' is the wordplay.
'poor' becomes 'mean' ('mean' can be similar in meaning to 'poor'**).
'time' becomes 't'.
'mean'+'t'='MEANT'
(Other definitions for meant that I've seen before include "planned" , "intimated" , "represented" , "proposed" , "Aimed" .)
