Sixty minutes outside disreputable bar in port (7)
I believe the answer is:
harbour
'port' is the definition.
(harbour is a kind of port)
'sixty minutes outside disreputable bar' is the wordplay.
'sixty minutes' becomes 'hour' (I've seen this before).
'outside' indicates putting letters inside.
'disreputable' indicates an anagram (I've seen this in other clues).
'bar' is an anagram of 'arb'.
'hour' placed around 'arb' is 'HARBOUR'.
'in' acts as a link.
(Other definitions for harbour that I've seen before include "mole" , "Dock" , "Shelter for ships" , "Ship haven or shelter" , "Secretly maintain - port" .)
