Link we’re to follow? There’s no time (5)
I believe the answer is:
nexus
'link' is the definition.
(I've seen this before)
I don't understand how the rest of the clue works.
(Other definitions for nexus that I've seen before include "Link - unsex (anag)" , "Connecting band" , "Unsex in connected group or series" , "Connected series; central point" , "Bond; meeting point" .)
