Had in mind low time (5)
I believe the answer is:
meant
'had in mind' is the definition.
('mean' can be a synonym of 'have in mind')
'low time' is the wordplay.
'low' becomes 'mean' (both can mean nasty).
'time' becomes 't' (abbreviation).
'mean'+'t'='MEANT'
(Other definitions for meant that I've seen before include "Had as purpose or design" , "Implied" , "Aimed" , "represented" , "no accident" .)
