Are you sure format-time-string is run in that case?

And calling select-window runs a different hook, doesn't it?

Anyway, do I really have to explain everything?  isn't it enough to
suggest a solution (assuming it is a solution)?

That's expected, since format-time-string needs to run as part of your
hook, not interactively, otherwise the recursion won't happen.
