Time to get friend to agree (5)
I believe the answer is:
Here is my best explanation:
'agree' is the definition.
('tally' can be a synonym of 'agree')
'time to get friend' is the wordplay.
'time' becomes 't'.
'to get' means one lot of letters go next to another.
'friend' becomes 'ally' (I've seen this before).
'to' acts as a link.
(Other definitions for tally that I've seen before include "Reckon up", "Mark", "List", "Square", "highly?", "Agree - count", "Record; current score", "Current score; agree", "Reckoning of a debt or of votes" and "Total score".)
