PS3 Change timestamp on a synchronized trophy

[LordQuas]

Hi, I unlocked a trophy that can't be unlocked anymore due to the servers off with PS3TrophyIsGood. That was the last one that I hadn't.
I put a timestamp that is coherent with the others trophies I unlocked.
The thing is, when I launched the game, I unlocked the platinum trophy and synchronize trophies before change the timestamp of the platinum's. So the timestamps between platinum trophy and the others are very spaced in time.

Is there a way to change the timestamp of the platinum trophy even if it's already synchronize to make it more coherent with the others trophies ?

I read that it's not possible, but if I reinstall the game and I put the same timestamps except for the platinum trophy with a oldest timestamp, is the timestamp of the platinum trophy will change ?
Is there a risk of ban ?

Excuse me if I made mistakes, English is not my native language.
Thank you for your answers.

Nobody can help me ?
I want to try to reinstall the game to have an empty trophy list completion and then unlock the trophies with the same time timestamps that before except for the platinum which I'll put an older timestamp that coincid with the last I unlocked.
But I scared of a ban.

You cannot change data on Sony servers side, and they have higher priority than data on console side.

Thank you, so there is no way to change the timestamp of a synchronized trophy ?

If You change it on console side, it will back to old data after synchronization because server have higher priority. As I said already. ;]
