pdfTeX (versions ≥1.40.17) support the use of
\pdfinfoomitdate to suppress the
/ModDate from begin written to the PDF.
I have searched for an equivalent method for XeLaTeX and XeTeX, but have not found anything. Did I miss it somewhere (if so, please present it here and point to where it is in the documentation)? Is there some alternative approach to accomplishing the same thing? Or is it not currently possible at all for XeLaTeX?
In case it is relevant, I am using
xdvipdfmx as the output driver.
