Is there any manipulate rewards from Pokemon Trainer Rematch in Pokemon HGSS?

[NamelessPlayah93]

I want to give me all evolution stone rewards after re-battle the pokemon trainer

here's the list

Dawn Stone - Biker Aiden 
Sun Stone  - Camper Tanner
Shiny Stone - Bird Keeper Josh 
Fire Stone  -  School Kid Alan 
Thunder Stone - Lass Dana 
Water Stone -  Fisherman Tully 
Leaf Stone - Picnicker Gina 
Dusk Stone - Biker Reese 

the problem is I've been rematching all of them by using manipulate day and time but still, they won't give me a reward.
