Facility can be arranged anytime (7)
I believe the answer is:
amenity
'facility' is the definition.
(thesaurus)
'arranged anytime' is the wordplay.
'arranged' indicates an anagram.
'anytime' with letters rearranged gives 'AMENITY'.
'can be' acts as a link.
(Other definitions for amenity that I've seen before include "This useful service" , "Desirable or useful feature of a place" , "Item provided to make life easier" , "Feature that makes life pleasant or convenient" , "type of hospital bed" .)
