forward RobTimers(playerid);

   SendClientMessage(playerid, -1, "ROBINFO: You're now can use the cmd '/robbank' again");
   robtimer[playerid] = 0;
}

CMD:robbank(playerid,params[])
{
   if(robtimer[playerid] == 1)
   return SendClientMessage(playerid, -1,"ERROR: You can use this command once every 30 minutes!");
   // bla bla bla
   robtimer[playerid] = 1;
   robplay[playerid] = SetTimerEx("RobTimers", // input for the minutes, false, "d", playerid);
   return 1;
}

I just imagine like that
