Punctual, eventually? (2,4)
I believe the answer is:
in time
This clue is a double definition.
'punctual' is the first definition.
('in time' can be similar in meaning to 'punctual')
'eventually?' is the second definition.
('in time' can be a synonym of 'eventually')
(Other definitions for in time that I've seen before include "What musicians aim to be" , "eventually" , "on schedule" , "not too late" , "What an orchestra should be" .)
