I believe the answer is:

sync

'agree in time' is the definition.
I can't judge whether this definition defines the answer.

'listening to founder' is the wordplay.
'listening to' indicates a 'sounds like' (homophone) clue.
'founder' becomes 'sink' (sinking is a kind of foundering).
'sink' sounds like 'SYNC'.

Can you help me to learn more?

(Other definitions for sync that I've seen before include "go together" , "In which things occur simultaneously" , "Unison (abbrev.)" , "In which one's matching" , "Agreement in time" .)

I've seen this clue in The Independent.
