Stretch and point across the pond (6)
I believe the answer is:
period
'stretch' is the definition.
(I've seen this before)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for period that I've seen before include "Time allocated for lesson in school" , "Stretch of time" , "Phase" , "Stop in America" , "Indefinite length of time" .)
