OP discusses Kolob, calls it a "world".
Orson Pratt, “Millennium,” The Latter-day Saints’ Millennial Star 28, no. 36 (September 8, 1866): 561
In the Book of Abraham, translated from Egyptian papyrus, by the Prophet Joseph Smith, is mentioned a certain world, called Kolob, whose diurnal rotation on its axis equals one thousand of our years. Kolob is represented in the scale of advancement, as being of that class of creations, next in order to celestialized worlds. Indeed, the inhabitants of one of the celestial creations measure their days by the diurnal rotation of Kolob. When eternal wisdom formed the earth, one thousand of its orbital revolutions, seem to have been adjusted to one axial rotation of the great time-keeper for the celestial hosts. Or, as the Apostle Peter has expressed it, "One day is with the Lord as a thousand years, and a thousand years as one day." Therefore, in comparing celestial with terrestrial time, it must be remembered that, one Kolob day is a Millennium.
