Quiet time/times embracing old attendant (7)
I believe the answer is:
pageboy
'attendant' is the definition.
(boy attending a bride at a wedding)
I cannot understand how the rest of the clue works.
(Other definitions for pageboy that I've seen before include "Youthful hotel attendant" , "Bride's attendant" , "Lad at wedding" , "Hairstyle - child at wedding" , "train supporter" .)
