Will observations ever be the same?

Interesting links, Pokey, thanks.

I think I would be right in saying that it is not time that is being manipulated, but the flow of information. Facinating stuff. I think the parting shot in the first link is significant:

Yes, definitely no time warping in that, but another very clever way to manipilate photons with a view (pun ) to deceive.
