I tried the obvious /from?site=*.fr but it doesn’t seem to be available
Or https://hn.algolia.com/api/v1/search_by_date?query=.fr/&rest...
See restrictSearchableAttributes=url in https://hn.algolia.com/api
Then maybe some JavaScript:
javascript:console.table(JSON.parse(document.body.innerText).hits.map(h => ({title: h.title, url: h.url, dt: h.created_at})))
The results aren't perfect. You could do more filtering on the client side.

but each TLD/subdomain have a different level of granularity.
It would be nice that if
https://news.ycombinator.com/from?site=co.uk
https://news.ycombinator.com/from?site=uk
also work and include all the subdomains.
