Couldn’t this just mean that they scanned the document and created the file on that date - meaning it still could be legitimate (but IMO it isn’t legitimate.)
I think we have seen this issue before on something it was just a matter of the person scanning and creating the file.
Yes, I think so.
http://en.wikipedia.org/wiki/Quartz_(graphics_layer)
Quartz specifically refers to a pair of Mac OS X technologies, each part of the Core Graphics framework: Quartz 2D and Quartz Compositor. It includes both a 2D renderer in Core Graphics and the composition engine that sends instructions to the graphics card. Because of this vertical nature, Quartz is often interchanged synonymously with Core Graphics.[1]
In a more general sense, the term Quartz or Quartz technologies can refer to almost every part of the Mac OS X graphics model from the rendering layer down to the compositor. In this use, the term covers Core Image and Core Video as well.[2]

Use of PDF
It is widely stated that Quartz “uses PDF” internally, often by people making comparisons with the Display PostScript technology used in NeXTSTEP (of which Mac OS X is a descendant) and OPENSTEP. Quartz’s internal imaging model correlates well with the PDF object graph, making it easy to output PDF to multiple devices.[6]
