For greater efficiency, pages are cached. You can force to render the
latest version by purging the page (just add ?action=purge to the url),
that's a bit faster than a null edit.

The fact that it sometimes work and sometimes not may depend on the
exact time the page being viewed was cached.

You may try {{#time: F}} {{CURRENTDAY}} in case it performs better.
