Has permission to collect passport needed by daughter at twelve (6)
I believe the answer is:
midday
'twelve' is the definition.
(I've seen this before)
'has permission to collect passport needed by daughter' is the wordplay.
'has permission to' becomes 'may' (I've seen this in another clue).
'collect' is an insertion indicator.
'passport' becomes 'id' (a passport is identification).
'needed by' says to put letters next to each other.
'daughter' becomes 'd' (genealogical abbreviation).
'id'+'d'='idd'
'may' going around 'idd' is 'MIDDAY'.
'at' is the link.
(Other definitions for midday that I've seen before include "1200 hours" , "12 o'clock in the day" , "12 noon" , "Twelve noon" , "time when hands are joined" .)
