That's correct, but it is not the complete story. The date search does
return a revision even if that revision is not "correct" is some sense.
However the date search works on the whole repository

   https://svn.apache.org/repos/asf

so the revision produced will often be one which didn't change
/subversion/trunk. That means that an empty log is shown just like
it is for this

   svn log -r1643098 https://svn.apache.org/repos/asf/subversion/trunk

Even when a repository does have strictly mototonic dates using log with
a single date will often show a blank log on non-root paths within the
repository.
