It seems so. What you are describing there had been noticed by Ian
Jackson before:
https://lists.debian.org/debian-devel/2016/11/msg00328.html
Ian then filed bug #843773 against sbuild, and as a result sbuild (as of
version 0.73.0-1) no longer reuses the timestamp of the last changelog
entry in binNMUs.
The same version of sbuild introduced a --binNMU-timestamp option, and I
think wanna-build should use it to achieve a consistent
SOURCE_DATE_EPOCH across architectures in binNMUs. Something along
these lines had already been proposed in #843773.
Cheers,
Sven
