Crossword Genius

Time to hire a river (5)

Ross

I believe the answer is:

trent

'a river' is the definition.
(River Trent)

'time to hire' is the wordplay.
'time' becomes 't' (abbreviation).
'to hire' becomes 'rent' (synonyms).
't'+'rent'='TRENT'

(Other definitions for trent that I've seen before include "River through Newark" , "Chief river of the Midlands" , "Midlands banker" , "Crossword frame" , "River at Stoke and Burton" .)

I've seen this clue in The Mirror.
