Spare time not disguised (5)


I believe the answer is:


'not disguised' is the definition.
(I've seen this before)

'spare time' is the wordplay.
'spare' becomes 'over' (left over).
'time' becomes 't' (abbreviation).

(Other definitions for overt that I've seen before include "Openly displayed" , "Open, not secret or hidden" , "Done in an obvious way" , "Obvious, patent" , "Clear" .)

I've seen this clue in The Times.
