Zero Hour: Crisis in Time was a miniseries that spearheaded DC's big 1994 crossover event Zero Hour. Zero Hour was designed to remedy continuity errors that had crept into DC titled since the Crisis on Infinite Earths, and relaunch all of the heroes from the same point in time. The Zero Hour event took place in a five-issue miniseries (numbered in descending order from 4 to 0), and with 27 crossover books, ranging from Action Comics to Wonder Woman. Showcase ’94 #8-9 served as a backstory to the event, highlighting the major villain Extant’s creation. Then Zero Hour : Crisis in Time #4-0 highlights the major story arc, including Hal Jordan’s first appearance since the Emerald Twilight story arc in Green Lantern. Issues were released in descending order, providing a "countdown" to the restart of the DC Universe.

Writer Dan Jurgens spearheaded the event, and wrote the five issue miniseries. He collaborated with individual writers, and, together with editor KC Carlson, coordinated all of the tie-in comics. Jurgens teamed up with Jerry Ordway to provide the artwork for the miniseries. Zero Hour: Crisis in Time #0 also featured a pullout three-page timeline of the “new” DC universe, designed by Brian Pearce. The unique Zero Hour logo, used across the miniseries, was designed by Tim Zach.
