List that is covering broadcast times (7)
I believe the answer is:
itemise
'list' is the definition.
(to itemise is to create a list)
'that is covering broadcast times' is the wordplay.
'that is' becomes 'ie' (short for Latin 'id est', 'that is').
'covering' is an insertion indicator.
'broadcast' is an anagram indicator (letters scattered or cast around).
'times' is an anagram of 'temis'.
'ie' placed around 'temis' is 'ITEMISE'.
(Other definitions for itemise that I've seen before include "break down" , "Set down separately" , "Read off list of things one by one" , "catalogue" , "Make a list" .)
