Fellow presenting information on time (4)
I believe the answer is:
gent
'fellow' is the definition.
(synonyms)
'information on time' is the wordplay.
'information' becomes 'gen' (gen can informally mean information).
'on' is a charade indicator (letters next to each other).
'time' becomes 't' (abbreviation).
'gen'+'t'='GENT'
'presenting' is the link.
(Other definitions for gent that I've seen before include "Toff" , "Informal and short man" , "Auctioneer's tool" , "cove" , "Refined man (colloquial)" .)
