When the build time and timezone vary, the resulting .pdf file includes
an embedded timestamp. It looks like doc/makefile attempts to make the
timestamp reproducible in the generated .pdf, but doesn't catch some
corner cases.
The patch to debian/rules sets FORCE_SOURCE_DATE, which is needed to get
texlive to respect SOURCE_DATE_EPOCH.
The other patch modifies doc/makefile to use SOURCE_DATE_EPOCH directly
rather than a reference timestamp file.
Thanks for maintaining libtommath!
live well,

Subject: [PATCH 1/2] debian/rules: export FORCE_SOURCE_DATE to allow .pdf
files to be generated reproducibly.
Without FORCE_SOURCE_DATE texlive does not respect SOURCE_DATE_EPOCH:
