What happens at noon? Reparation (6)
I believe the answer is:
amends
'reparation' is the definition.
(both can mean making up for doing something wrong)
I don't understand the rest of the clue.
(Other definitions for amends that I've seen before include "Changes for the better" , "Make these to atone for wrong done" , "Make these to make up for past wrongs" , "They're made to compensate" , "Make these to atone for injuries or loss caused" .)
