Hello again.<br>
<br>
The most official thing I can get by now, is the following tweet
from Rocio Nahle, who is the current Secretary for Energy, which
shows the change for America/Chihuahua:<br>
<br>
<a class="moz-txt-link-freetext" href="https://twitter.com/rocionahle/status/1585682205417799688">https://twitter.com/rocionahle/status/1585682205417799688</a><br>
<br>
In the picture, Chihuahua (the one on the top left) is now shown in
the same timezone than Mexico/General. It also shows that, for some
municipalities in the border with USA (such as America/Ojinaga),
they'll keep the DST.<br>
<br>
I'd love to bring some more official info than a tweet, such as a
the publication on the Official Journal of the Federation, but the
thing is it hasn't been published yet; still most of the media, and
as seen, even the Secretary for Energy (who actually manages the
time issues in Mexico), are speaking about this as a given. Most of
the users in this area (America/Chihuahua) are indeed expecting for
this to happen.<br>
<br>
<p>Greetings.</p>

<pre>Thing is, there are certain regions which will get a change on its DST as soon as October 30th, 2022.
This is the case for Chihuahua (America/Chihuahua) which seems wont change its time this sunday, as it'll be aligned to Mexico/General, again, this same October 30th, 2022, according to this same law.

<div>That is good to know. So far, our understanding had been
that ALL regions would fall back on 30 October (or 6
November, for those that follow US rules) as originally
scheduled, and therefore that we would have until 2 April
2023 before the change affected any timestamps. But if any
regions are indeed changing zones by NOT falling back this
weekend, that is a different story and we should work to get
that into a release as soon as possible.</div>
<div><br>
</div>
<div>Do you have a clear reference for which regions will
be doing this? Perhaps a comparison of the regions listed
in the recently approved law and the previous law it
replaces?</div>

<pre>This sets what I think are really hard implications for most of the services running on this timezone.
If the said law is published between now and next Saturday, I guess it'll be havoc among users on this timezone.
I still don't think there's an easy fix from tz to this, but I think it's important for somebody to notice this.</pre>

<div>Yes, and it underscores the importance of allowing
sufficient time to allow changes to be clearly communicated,
encoded, tested, published, and propagated to end-users. This
issue is well familiar to frequent readers of this list, but
remains somewhat less familiar to the governments of the
world.</div>
<div><br>
</div>
<div>Even if we're able to get a release out in the next ~40
hours before this happens, by this point, it's unlikely to get
to most end-users in time.</div>
