D&C 132
Peter spoke of -
"...the times of restitution of all things, which God hath spoken by the mouth of all his holy prophets since the world began." (New Testament | Acts 3:21)
The Lord told the Prophet Joseph Smith -
"I am the Lord thy God, and I gave unto thee, my servant Joseph, an appointment, and restore all things. Ask what ye will, and it shall be given unto you according to my word." (Doctrine and Covenants | Section 132:40)
Adding -
"For I have conferred upon you the keys and power of the priesthood, wherein I restore all things, and make known unto you all things in due time." (Doctrine and Covenants | Section 132:45)
It becomes clear that Joseph Smith was commanded to restore all things as directed in due time.
