I'm not aware of a software that lets the author pre-date an article. This is indeed strange and just raises more questions. I don't know about the rest of the world but I for one don't believe CNN when i know it is noon and they "well its noon". I have seen them green screen fake videos and even can recall the Bush Oraq invasion when they faked stuff from the roof top of CNN Center in Atlanta with fake air sirens and the works.

CNN in garbage. Now that being the case if this is a false flag then CNN would be a willing participant.
