        <div class="gmail_extra">The tz project neither defines nor
          tracks zone boundaries; however, it is sometimes helpful to
          think of zones in this manner.  Obviously such boundaries
          would change upon the creation of a new zone.  You could make
          the case that such boundaries would also change if it is
          discovered at some point that location A better matches zone X
          than zone Y, but as long as location A is not itself defined
          in zone.tab, this does not affect tz data, and thus does not
          concern the tz project beyond documenting appropriate
