Next time (6)
I believe the answer is:
second
This clue is a double definition.
'next' is the first definition.
(thesaurus)
'time' is the second definition.
(unit of time)
(Other definitions for second that I've seen before include "Silver medal position" , "Moment; musical interval" , "Helper in the ring" , "taking silver back" , "Moment in time" .)
