The point at the time (4)

I believe the answer is:

then

'at the time' is the definition.
('then' can be a synonym of 'at the time')

'the point' is the wordplay.
'point' becomes 'n' (N is an example**).
'the'+'n'='THEN'

(Other definitions for then that I've seen before include "Once upon a time" , "Consequently" , "At that time; next" , "Afterwards - as a result" , "Subsequently - previously" .)

I've seen this clue in the Evening Standard.
