Thank you very much for checking reproducibility: almost nobody does.
Try setting the TZ environment variable to UTC:
export TZ=UTC
These differences seem confined to the modification timestamp of the ZIP
file, which should be equal to the one in the POM file:
<project.build.outputTimestamp>2025-11-06T21:58:17Z</project.build.outputTimestamp>
but expressed in your local time zone.
We have a tacit convention with Gary (from one of the previous builds)
that Gary sets its time zone to UTC during the release process and I do
the same during verification.
