About time; secular (8)
I believe the answer is:
temporal
I believe this clue is a double definition.
'about time' is the first definition.
(I've seen this before)
'secular' is the second definition.
(I know that secular can be written as temporal)
(Other definitions for temporal that I've seen before include "Nothing spiritual" , "profane" , "Of wordly affairs, not spiritual" , "Relating to time" , "Passing" .)
