Not portable.  See

And yeah, this is a Debian mailing list, but there's no compelling
reason to use an obtuse %F option that you'd have to rewrite for other
systems when it doesn't increase readability over %Y-%m-%d which
everyone can easily understand.

Fun with non-Debian systems:

imadev:~$ date +%F
imadev:~$ gdate +%F

(%F is listed as "Obsolescent" on this system; the man page says to use
%B instead.  gdate is GNU date, compiled from sh-utils source long ago.
Before it became part of GNU coreutils.)
