In all criminal prosecutions the accused shall have compulsory process for obtaining witnesses in his favor. The compulsory process shall be in misdemeanors a subpoena under the official signature of the clerk of the court or other judicial officer. Such subpoena or a copy thereof shall be served upon the witness a reasonable time before such witness is required to attend court. For any disobedience to such subpoena the court may punish for contempt.
