Thats why Google knows it needs to gravitate in its direction and offer as fresh of results as possible, particularly when relevant.
Google already has a sorted by date feature under recent results in its list of search options that users can use to customize their search experience. The jury is still out on how frequently these search options are and will be used, but that options there, and chances are that it will get better at indexing fresh content. Chances are also that more and more people will realize that option is available. It hasnt been around that long yet.
