Open extra time (5)

Ross

I believe the answer is:

overt

'open' is the definition.
(associated in meaning)

'extra time' is the wordplay.
'extra' becomes 'over' (both can mean left over).
'time' becomes 't' (abbreviation).
'over'+'t'='OVERT'

(Other definitions for overt that I've seen before include "Open and obvious" , "Plain and obvious" , "Open, not 1 across" , "____ is able to be seen" , "Openly displayed" .)

I've seen this clue in The Hindu.
