Dear maintainers,
gtkdoc-pdf, and possibly other gtk-doc tools, seems to embed the build day in
their output. This makes all packages that use it for generating documentation,
build unreproducibly.

This happens despite the package not doing anything date-related in its gtk-doc/
and gtkdoc-mkpdf seems not to provide any CLI parameter to override the date.
Please consider adding such a parameter, *and* default to honouring the
environment variable SOURCE_DATE_EPOCH if it is defined:
https://reproducible-builds.org/docs/source-date-epoch/
Best,
nicoo
