Time to follow Times, in time producing a special edition (5)
'a special edition' is the definition.
(I've seen this before)
'time to follow times in time' is the wordplay.
'time' becomes 't' (abbreviation).
'to follow' is a charade indicator (letters next to each other).
'times' becomes 'x' (multiplication sign).
'in' is an insertion indicator.
'time' becomes 'era' (era is a kind of time).
't' put after 'x' is 'xt'.
'xt' placed inside 'era' is 'EXTRA'.
'producing' acts as a link.
(Other definitions for extra that I've seen before include "One playing a minor part", "Ancillary", "Surplus to requirements", "Studio crowd player", "more than required".)
