When Does "The World of Krypton" #2 (1987) Take Place?
"The World of Krypton" #2 v2 "After the Fall" is a science fiction comic-book written by John Byrne and released September 15th, 1987.
We know this because an omnipotent narration textbox tells us that “Even after a thousand years…” (from Kal-L/Clark Kent/Superman's ancestor Van-L’s point-of-view) referring to something that happens halfway through this issue. The first half of the issue follows immediately from the final page of the previous issue, "The World of Krypton" #1 v2 (1987), which takes place entirely in 99046 BC.
It takes place on an alternate timeline of the fictional DC Comics Universe in the year:
98046 BC

-99,046 + 1,000 = -98,046.
So 'the present' in this issue is 98046 BC but Van-L spends the first half of the comic remembering what the reader perceives as a flashback to the start of the Kryptonian Civil War "a thousand years" earlier in 99046 BC.
Later, in "The World of Krypton" #3 v2, the events of issue #1 (which follow into this book in the flashback) are also referred to by an A.I. as occurring “in the year 105/892 of the Fifth Age”. Presumably, 105/892 of the Fifth Age is the equivalent year on a Kryptonian calendar.
This comic-book was retroactively collected into a "Superman: The World of Krypton" paperback and then collected again into a later, expanded "Superman: The Many Worlds of Krypton" paperback.
It is the chronologically second-earliest comic in the DC Comics Universe multiverse timeline (a chronological second comic to feature Kryptonians) and can be read after the previous issue, "The World of Krypton" #1 v2 (1987).
