Hi Karl, I committed a similar patch to the attached one in Gnulib so I will copy my rational from there [1]:
> I wanted to make a change to the bootstrap script but every time I saved > the file Emacs would open a new window with an annoying warning. This is > because of the following change documented in Emac's etc/NEWS: > > *** Some historical 'time-stamp' conversions now warn. > 'time-stamp-pattern' and 'time-stamp-format' had quietly accepted > several 'time-stamp' conversions (e.g., "%:y") that have been deprecated > since Emacs 27.1. These now generate a warning with a suggested > migration. > > Based on the 'git blame' it appears "%Y" was supported decades ago, so I > don't expect changing this to cause any trouble. Therefore, I have > pushed the attached patch. The old convention still exists in Gnulib files and files imported from other places. I have left them unchanged since we do not modify them and just modify them with 'make fetch'. Collin [1] https://lists.gnu.org/archive/html/bug-gnulib/2025-06/msg00093.html
