--- Comment #6 from anlauf at gcc dot gnu.org --- If you do not want to use non-portable extensions (try: -std=f2023 to see that it is not a Fortran standard procedure), or write a wrapper around date_and_time and friends, you may have a look at pr82480 for a solution that avoids using bad options like "-fdefault-integer-8".
