Hi.  I was seeing CI/CD failures shortly after midnight:

copyright_check
./gnulib/lib/version-etc.c
maint.mk: out of date copyright in ./gnulib/lib/version-etc.c; update it

I have pushed the patch below to work around the problem.

I wonder how timezone-safe this is -- maybe some other test will now
fail for someone in the US before it actually becomes midnight there?

/Simon
