Subject: [PATCH] Fix date for Ubuntu >= 25.10 (3.2)

Ubuntu 25.10 has transitionned from GNU Core-utils to Rust Core-utils. That changes the testing
results which date version to use for displaying / conversion of dates like in certificates.
Probably more Linux distriutions will follow. See also #2909 .

For maintenance reasons it is advised also the stable version will get this patched. For
3.3dev, see #2913 .
