Time for everyone to pass on knowledge (5)
I believe the answer is:
teach
'pass on knowledge' is the definition.
(I've seen this before)
'time for everyone' is the wordplay.
'time for' becomes 't' (I've seen this in other clues).
'everyone' becomes 'each' (I've seen this in other clues).
't'+'each'='TEACH'
'to' acts as a link.
(Other definitions for teach that I've seen before include "train" , "Impart skills or 3 down" , "Blackbeard" , "Work in school" , "Coach" .)
