Sorry, I meant DATE_AND_TIME here.

I think the origin of the bug is:

void
gfc_resolve_ltime (gfc_code *c)
{
  c->resolved_sym
    = gfc_get_intrinsic_sub_symbol (gfc_get_string (PREFIX ("ltime_i%d"),
                            gfc_default_integer_kind));
}


This always uses the ITIME version corresponding to
gfc_default_integer_kind, disregarding the actual kind of the
arguments.

Cheers,
Janus
