Once I got time for leave (4)

Ross

I believe the answer is:

exit

'for leave' is the definition.
(synonyms)

'once i got time' is the wordplay.
'once' becomes 'ex' (prefix meaning former or onetime).
'got' means one lot of letters go next to another.
'time' becomes 't' (abbreviation).
'ex'+'i'+'t'='EXIT'

(Other definitions for exit that I've seen before include "Withdrawal" , "[DOOR] ?" , "Depart" , "Player's departure" , "Sudden rush of pleasure" .)

I've seen this clue in the Evening Standard.
