Hi,

I'm currently making PDF documentation from a Makefile:

> TEXMACS_CONVERT = env "HOME=$(abs_builddir)" xvfb-run --auto-servernum 
> -- texmacs
>
> doc/scheme-gnunet.pdf: doc/scheme-gnunet.tm $(tm_fragments)
>     $(TEXMACS_CONVERT) -c "$<" "$@" -q
The problem is that the generated PDF embeds a timestamp, which hinders 
reproducible builds (https://reproducible-builds.org/):

> $ guix shell xxd poppler diffoscope -- diffoscope 
> doc/scheme-gnunet.pdf  2.pdf

> --- doc/scheme-gnunet.pdf
> +++ 2.pdf
> │   --- doc/scheme-gnunet.pdf

Question: how can I ask TeXmacs to set the creation date to something 
else (e.g. 1970-01-01) or leave it out entirely?

Greetings,
Maxime.
