Frogman with time to entertain (6)
I believe the answer is:
divert
'entertain' is the definition.
(diverting is a kind of entertaining)
'frogman with time' is the wordplay.
'frogman' becomes 'diver' (synonyms).
'with' means one lot of letters go next to another.
'time' becomes 't' (abbreviation).
'diver'+'t'='DIVERT'
'to' is the link.
(Other definitions for divert that I've seen before include "Amuse, or turn from normal course" , "Amuse or send in another direction" , "Delight" , "Find a different way" , "offer entertainment" .)
