Writer Scott Snyder has addressed whether the 2013-2014 Batman storyline "Zero Year" is still DC comics canon.

With the sometimes-nebulous continuity of the core DC Universe, it can be difficult to know whether certain stories remain as part of the current Rebirth era. The publisher's 2011 reboot the New 52 erased decades of continuity for some characters and titles, but carried through the history for others.

But with the fictional universe facing more changes brought about by the events of Justice League and Doomsday Clock, one fan asked Snyder whether the events of "Zero Year," which redefined Batman's origin, are still considered part of the established timeline.

It's all supposed to be right now. Bc of what's happening in Doomsday Clock, there can be fluidity so a lot of pre and post new 52 material co exist. Also, I always feel Bruce wore the great classic costume most of his early career. ZY is specific to ZY.— Scott Snyder (@Ssnyder1835) August 16, 2018

“It's all supposed to be right now," Snyder replied on Twitter. "[Because] of what's happening in Doomsday Clock, there can be fluidity so a lot of pre and post new 52 material co exist. Also, I always feel Bruce wore the great classic costume most of his early career. ZY is specific to ZY.”

Writer Tom King has briefly explored the early years of Batman’s career in his current run on the title, with allusions to "Zero Year." However, the series also reflects the Golden Age and post-Crisis versions of how Batman and Catwoman met. Snyder's answer also suggests a malleability to the current timeline brought on by Doomsday Clock. It seems that the DC/Watchmen crossover might have a greater effect on the DC Universe than some fans expected.

Doomsday Clock #7, written by Geoff Johns and illustrated by Gary Frank, is scheduled to be released on Sept. 26.
