What exact queries are you using?

This is possible.

  http://live.gnome.org/Tracker/Documentation/SparqlFeatures

In particular the XPath date and time section.

Are you using regex?

Yes.

No the first is not related, the second is not a bug but probably a
query failure.

For more clues, see the Tracker source for src/miner/fs and even
src/tracker-utils/
