There are no old ones nowadays (5)
I believe the answer is:
times
'nowadays' is the definition.
(times is a kind of nowadays)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for times that I've seen before include "Paper" , "Square in New York" , "Paces" , "Newspaper - X" , "- - they are a-changin'" .)
