A Google Web Search Help thread has complaints from some Google searchers that there is a weird bug on Google News when using the date range advanced search option.
When you go to Google News and restrict the search to a specific date range, for some people, it is inverting the date you specified and thus not using the date range you entered for your query.
The issue is, when you enter it in the format of day/month/year it changes it to a month/day/year format and then breaks the search.
Here is a video demo of the issue:
