I see. Then maybe showing he problem from `emacs -Q' requires a more
carefully-crafted example.

But this doesn't work when I run Emacs normally, and in that case I'm
not doing anything unusual. I don't know when time.el is loaded with
respect to when my init file is run. But even if I comment out my entire
init file except for this snippet, this problem occurs.

I can't change the order because Customize puts its variables in
alphabetical order.
