Not take one's time (4)

I believe the answer is:
rush
'not take one's time' is the definition.
('rush' is the opposite to 'take one's time')
This is the entire clue.
(Other definitions for rush that I've seen before include "Charge" , "Drug-induced euphoria" , "Reed" , "Hurry; grasslike plant" , "Marsh plant - fly" .)
