Change the date of written messages?

[Goodman_2020]

Hi

Is there a possiblity to change the date of each messages written (via a template edition or i don't know what)?
Im creating a new forum, and i try to create a fake activity, so i need to make believe to potential visitors that the message have not been posted just few time ago....because if they see that there is 300 messages and that they all be written since last week they will guess it's fake activity you know what i mean?

Thanks if somebody knows how to do that

i found a hack doing that, the thread can be closed.
