The question how to create identical PDF files with pdflatex was basically answered in this question already:
How to create identical PDF files?
The catch was to filter out the entry /ID in the trailer dictionary after the PDF file was created.
I am now forced to use xelatex and there this trick does not work any more, because there are many more changes in the resulting PDF files.
Here is the minimal working example again:
documentclass[11pt,a4paper]article
usepackage[]hyperref
hypersetup
pdfauthor=None,
pdfcreationdate=D:20131010120000,
pdfmoddate=D:20131010120000
begindocument
foo
enddocument
If I now create 2 PDF files, convert them to a hex dump and view the differences...
xelatex mwe.tex; mv mwe.pdf a.pdf; xxd a.pdf > a.bin
xelatex mwe.tex; mv mwe.pdf b.pdf; xxd b.pdf > b.bin
diff -u a.bin b.bin
... then you can see that there are many differences in the resulting PDF files unfortunately.
Is there any way to produce bitwise identical PDF files with xelatex?
The reason I need this is that I'd like to create PDF files for a software release package. Of course the software release package should be identical when the underlaying software and documentation has not been changed.

with recent Texlive releases you can use
SOURCE_DATE_EPOCH=0 FORCE_SOURCE_DATE=1 xelatex pp407
You may also want to set
SOURCE_DATE_EPOCH_TEX_PRIMITIVES=1
the first setting is the epoch setting. That is, the number of seconds since 1970.
E.g., for today (rather than 0 which is the 1st Jan 1970) you could use 1505482364 as found by:
$ date +%s
1505482364
The second if set to 1 (or anything) causes tex commands such as year to use the specified epoch date rather than the system clock.
The combination of two of them produces reproducible results (after the second run) in texlive2017 using the supplied test file.
First run:
SOURCE_DATE_EPOCH=0 FORCE_SOURCE_DATE=1 xelatex pp407
produces:
Package hyperref Warning: Rerun to get /PageLabels entry.
second run
SOURCE_DATE_EPOCH=0 FORCE_SOURCE_DATE=1 xelatex pp407
produces:

I use a script to create a release from a software: it gets the software from a GIT server, then creates the documentation using xelatex, then puts all this together in a ZIP. If nothing has changed, the result should be bitwise identical. If the PDF documentation is handled under version control as well, then running the script changes the PDFs every time. GIT will then think that the PDF has changed, but they haven't. It's annoying.
