There’s a somewhat famous storyline in the swamp thing comics where, by communing with plants, Swamp Thing ends up as the cross Jesus was crucified on. In other words, yes ST is timeless.
Swamp Thing: "Are you ready to go? Cuz I'm ready to go."
Jesus: "What ya gonna do, baybay baybay?"
Swamp Thing: "....Eh, we'll talk about it, um, during supper..." 😔
