Time to jump (6)
I believe the answer is:
spring
This clue is a double definition.
'time' is the first definition.
(time of year)
'jump' is the second definition.
(I know that spring is a type of jump)
'to' is the link.
(Other definitions for spring that I've seen before include "Start season" , "split" , "Bound into the season" , "Pounce -- pogo stick part" , "See 11" .)
