Multiverse explains "time differences"?

With the recent intel being released and the possibility of multiverses (  Where There Was One ) perhaps this will explain what has been one of three major mysteries I have held onto since the early days of Niantic - The Arecibo date and Devra

In this audio - Devra mentions Arecibo and '84 http://commondatastorage.googleapis.com/pac/IB/00/item/contact/Contact.mp3

But the later meeting between Hank and Devra in Areicbo takes place in 1995  - https://plus.google.com/+NianticProject/posts/PZJPAZmZHsN

So... a goof, a time shift, or multiverse bleed thru??  We are in interesting times.

PS as to the other mysteries - I am still waiting for Cognidyne and Hollis to be explained :)
