Background

, and was indeed subtitled "(A) Crisis in Time". It promised to do for the inconsistent future timelines of the DC Universe what Crisis had done for its parallel worlds: unify them into a new one.

This event served as an opportunity to reconcile some of the problems left unaddressed by Crisis and other problems that had been unintentionally caused by it. In particular, the revised characters of the post-Crisis universe had been rolled out gradually, with DC continuing to feature the old versions until the new versions were launched, some of them a year or several after the first wave of revised characters were published (i.e., The Man of Steel, Wonder Woman vol. 2

This "blanking out/recreation" of the DC Universe was reflected in many of the tie-in issues; near the end of several of the tie-ins, the world began to disappear, and the last page of the book (or in some cases, several pages) had been left blank.

Aftermath

DC published a fold-out timeline inside the back cover of Zero Hour #0 which identified various events and key stories which were part of its newly singular timeline, and when they occurred. Although fixed dates were given for the debut of historical characters such as the JSA, the debut of the post-Crisis Superman was presented as "10 years ago" and subsequent dates were expressed the same way, suggesting that the calendar years of these events were fluid and relative to the present rather than fixed

But this "warm reboot" did not solve all continuity matters and in fact actually created other continuity problems— the fold-out timeline included Armageddon a story that required the supposedly eliminated alternate timelines to even work, Matrix Supergirl who required an artificially created alternate timeline still existed, and "Who is Hawkman?" actually became less clear. Never mind that some fans and creators felt that multiple worlds and timelines were an asset (rather than a hindrance) to the DC Universe. For those and other reasons, DC later introduced a variation of the pre-Crisis concept of the Multiverse
