After the trial has commenced, before or after the jury is sworn, the court may order the jurors to be kept in charge of proper officers, or they may be permitted to separate during the trial. If the jurors are kept in charge of officers of the court, proper arrangements shall be made for their care, maintenance, and comfort, under the orders and direction of the court. In case of necessity the court may permit temporary separation of the jurors.
