Time and motion list (6)
I believe the answer is:
agenda
'list' is the definition.
(I know that agenda is a type of list)
'time and motion' is the wordplay.
'time' becomes 'age' (an age is a period of time).
'motion' is an anagram indicator.
'and' with letters rearranged gives 'nda'.
'age'+'nda'='AGENDA'
(Other definitions for agenda that I've seen before include "Schedule, order of business" , "Programme of a meeting" , "Schedule - things to be done" , "List of business for a committee meeting" , "Menu" .)
