Whenever an arrest is authorized by the provisions of this Code, it may be made on any day and at any time of the day or night. NOTE: Section 20.30 supersedes former § 840. Compare Cal. Pen Code § 840. See generally B. Witkin, California Criminal Procedure Proceedings Before Trial § 109(1963, Supp. 1973). The major change is to authorize misdemeanor arrests by a peace officer at any time on reasonable cause without the additional requirement of a threat of flight or additional injury.
