When Does "Harbinger" #7 (1992) Take Place?
"Harbinger" #7 v1 "Flowers for the Living" is a superhero comic-book written by Jim Shooter that released April 14th, 1992. So when is "Harbinger" #7 set?
It takes place on the fictional Valiant Universe timeline in the year:
We know this because a tombstone appears for a character that died in the previous issue "Harbinger" #6 v1 (1992) and it reads: "1972 - 1992".

1992 AD
We know this because a tombstone appears for a character that died in the previous issue "Harbinger" #6 v1 (1992) and it reads: "1972 - 1992".
Furthermore, early on there is a time setting textbox reading: "Monroe, Louisiana, March 7, 1992, 1:31 A.M." and one on the final page tells us we are now "Somewhere in Alabama, March 16, 1992, 5:59 P.M." So presumably it is March of 1992 AD.
This comic-book was retroactively collected into a "Harbinger" volume 1 subtitled "Children of the Eighth Day" and another subtitled "The Beginning".
It is an early chronological comic-book in the Valiant Universe (a chronologically ninth comic to feature the Harbinger characters) and can be read at its timeline point.
