   Looks like a bug in `elpa-admin.el` in how it extracts the commit date
   to generate the <release>.0.<date>.<time> version number used for
   GNU-devel.

Seems like non-portable date usage, OpenBSD date doesn't have the -d
switch -- this should probobly have some error maybe?

  call-process git ("show" "--pretty=format:%cI" "--no-patch")
  call-process date ("-d" "2021-09-28T09:18:26+02:00" "+%Y%m%d.%H%M%S")
