Destroy NewTimer

    NewTimer("BLABLA", 1000, 30, player.ID);

    function BLABLA( player )
    {
            local p = FindPlayer( player );
            if ( TeleTime[p.ID] < 1 ) return TeleTiempo( p );
            else if( TeleTime[p.ID] > 1 ) return TeleTime[p.ID]--;
    }

if player is disconnected is a great fail. How I can destroy this newtimer?
