A question about the upcoming 'Doomsday clock'

Before I ask the question let me just say that I've started watchmen and after weeks of hunting it down, the wait was most definitely worth it, anyway. so I've started reading the weekly series's, but I've limited myself to only 2: Batman and Justice League. I'm excited for Doomsday Clock and I'm just wondering will it be part of the Justice League Rebirth line?
