To be more precise, dates are resolved to revision numbers using binary search on the revisions space, comparing by the svn:date revprop's value; that process can give different answers over time (as HEAD increases) if the sequence of svn:date values isn't monotonically increasing, which can happen, for instance, when doing 'svnadmin load' into an existing repository.
