It seems to work for me at the moment for that particular test:
$ svn log -q -r {2005-10-1} http://svn.apache.org/repos/asf

However, the binary search that Subversion performs probably depends
on how many revisions are in the repository at the moment you do the
query. As revisions are constantly being added, the specific searches
that will fail will vary. You should not expect a date revision
search to be reliable in the ASF repository, because their revisions
are not all in chronological order, per:
