If you open the document in Acroread its content is rendered correctly using Times font.
IcePDF for some reason uses Arial instead (however in doc font info it still refers to Times).

As for me it is a bug of IcePDF, or its free version restriction (which does not include a font engine, according to the download page).

I would recommend to generate PDF with TTFs embedded, not relying to built-in viewer fonts.
