Hello Akira,

export SOURCE_DATE_EPOCH=`perl -e "print time();"`
export FORCE_SOURCE_DATE=1
for i in 1 2; do

mv valuators.pdf valuators${i}.pdf
sleep 2
done

%valuators.tex
\documentclass{article}
\usepackage{graphicx}
\begin{document}
Hello.

\includegraphics[width=8cm]{valuators.png}
\end{document}

where valuators.png is obtained from

pdflatex -interaction=batchmode "\pdfinfo{/ CreationDate(D:20260429034606Z)/ ModDate(D:20260429034606Z)}\input{valuators.tex}" https://salsa.debian.org/fltk-team/fltk1.4/-/blob/main/documentation/ src/valuators.png?ref_type=heads

Many thanks for pointing that out! Until now I was happy, that I could reproduce the issue at all, did not find the time yet to create a minimal example...or say better I did not try b/c the OP told it would not that easy. ;-)
