Nod - automated mashups of that kind are outside of the ability of
<time>, even if extended to handle those dates. It seems that the
useful things to do are:
* directed mashups, where you can manually point an app at particular
dates that you catch across the web and automatically slurp them.
* more reliable temporal searching, at least for pages that include
this kind of markup. Rather than just searching using "2000 BC" or
whatever and hoping that the target page includes that phrase, the
search engine could also take note of manually encoded times and use
these to help filter the returned results
