The magistrate or judge shall also enter on the face of the original warrant the exact time when the warrant was ordered to be issued.
(3) The duplicate original warrant shall be returned according to section 29-815. Upon the duplicate original warrant being returned, the magistrate or judge shall sign it and shall file it, together with the original warrant, in the same manner as that required under section 29-816.
