It has never really concerned itself with where any borders between those regions are, no matter how simple or complex.<br><br></div><div class="gmail_extra">However, if there were a historical case where a region once observing DST decided to stop, or a region once not using DST decided to start, then that would be codified as a new zone, since the rulesets would differ from both America/Denver and America/Phoenix. But perhaps if only a small handful of people are affected by these effective border changes, it <i>may</i> be too insignificant to bother.<br></div><div class="gmail_extra"><br clear="all"><div><div class="gmail_signature">--<br>Tim Parenti<br></div></div>
