dont bump its against the rules!!

pawn Код:

forward dissablecmd(playerid);
public dissablecmd(playerid)
{
KillTimer(Timer);
CMDClass[playerid] = 1;
SendClientMessage(playerid,COLOR_LIGHTBLUE,"/class time is over");
print("/class time is over");
return 1;
}

try that

edit also you should be using SetTimerEx

pawn Код:

Timer = SetTimerEx("dissablecmd",30000,false,"i",i);
