Well, whether or not it should make this assumption is arguable, but the
fact is that it does make this assumption.

From subversion/libsvn_repos/rev_hunt.c:

/* Note: this binary search assumes that the datestamp properties on
   each revision are in chronological order. That is if revision A >
   revision B, then A's datestamp is younger then B's datestamp.

   If some moron comes along and sets a bogus datestamp, this routine
   might not work right.

   some semantic checking when it's asked to change special reserved
   svn: properties. It could prevent such a problem. */
