Bug#1121862: goobook: please make the build reproducible

[Chris Lamb]

Source: goobook
Version: 3.5.3-2
Severity: wishlist
Tags: patch
User: reproducible-builds at lists.alioth.debian.org
Usertags: timestamps
X-Debbugs-Cc: reproducible-bugs at lists.alioth.debian.org

Hi,

Whilst working on the Reproducible Builds effort [0], we noticed that
goobook could not be built reproducibly.

This is because the call to modify the mtime of the README.txt file
could be overwritten by the general 'clamping' of timestamps to the
"maximum" of SOURCE_DATE_EPOCH.

A patch is attached that uses the value of SOURCE_DATE_EPOCH instead
of the "2025-09-14 10:00:00" value.
