Excelent work. You missed Uruguay, who went throw something very similar to what turkey went through but a couple of months before. Actually, what happened in Uruguay and the inability of government officials to even understand what went wrong is what brought me here to this mailing list.

Interesting. I notice that you didn't ask for clarity in the announcements about the time when the transitions occur, but that is a common cause of concern to the TZ community. Would it be worth adding that? -- Jonathan Leffler <jonathan.leffler@gmail.com> #include <disclaimer.h> Guardian of DBD::Informix - v2015.1101 - http://dbi.perl.org "Blessed are we who can laugh at ourselves, for we shall never cease to be amused."

That's an excellent idea. Added to the list of recommendations in the article.

Thanks!

Just an onlooker... but if you changed the policy to an automatic 90 or 180 delay between notice of tz change and public release of new databases versions... that would tend to draw public attention to violations of the policy.

That would be causing pain to people who can do little about it. While deeply satisfying, it would be the wrong thing to do for our users. See the list of countries that make these last-minute changes, and look them up on the a Transparency or Freedom list. -- Sanjeev Gupta +65 98551208 http://www.linkedin.com/in/ghane

I'd be against this. It would result in more use of unofficial and unreleased data, or manual hacking of downstream systems.

A better plan is to work on two fronts: 1) Increase awareness so that governments might try to provide more lead time in the future, and 2) work on technical solutions to improve distribution of tz data, reducing the amount of lead time necessary (which varies per implementation).

Yes, I am fine with anyone translating and republishing as long as appropriate credit and linkback are provided.

Well, it took me 3 months (actually, it took me a week in the hospital and away from work which allowed me to concentrate in this), but I did translate your excelent post into Spanish. It is at https://clueless.com.ar/acerca-del-momento-en-que-se-anuncian-los-cambios-en... and, as you can see at the top, I credited you and linked to the original post (if you want me to change anything about this, just tell me so). I also added a personal addendum in the end (and clearly marked as mine) to refer to the years when my country did the wildest things about timezone changes.
