This week I was working to make the toolchain package texlive-bin
produce reproducible PDF files. A patch was submitted to the responsible
upstream, pdftex, and is currently being discussed.
Upstream patch: http://tug.org/pipermail/pdftex/2015-July/008952.html
The patch honours the environment variable SOURCE_DATE_EPOCH which was
proposed by the Debian reproducible builds team as a way to have
deterministic timestamps .
I reported bugs against Doxygen and texlive-bin in Debian in order to
keep track of the progress of the upstream bugs.
I updated the wiki entries where we are documenting the Doxygen  and
texlive-bin  issues to include the information about the use of
SOURCE_DATE_EPOCH and the bugs I filed upstream.
