User cant post in specific hour

[BenH]

I've no idea whats going on .. when i posted the replay , it didnt work , when i checked agian after seeing your replay it worked , now its not working agian ..
i checked the server time and the usergroupid
the code i have is

// Moderate Users Hack
if ($bbuserinfo[usergroupid]==46 AND (int)date("H", time())>21 AND (int)date("H", time())<9)
{
$visible=0;
}
// Moderate Users Hack

it just put the post / replay and doesnt add this to the queue

thanks alot
Ben
