IATA and ABEAR argue that the DST change will afect 3 millon people that travel by airplane on affect period. We had elections in Brazil yesterday, including for president. So all the attention was on that, may be this week we will have an official decision. More two sources: https://veja.abril.com.br/economia/companhias-aereas-reclamam-de-nova-alteracao-no-horario-de-verao/ http://agenciabrasil.ebc.com.br/economia/noticia/2018-10/aereas-dizem-que-mudanca-no-horario-de-verao-vai-prejudicar-passageiro Em seg, 8 de out de 2018 ?s 16:02, Matt Johnson < mj1856@hotmail.com< mailto:mj1856@hotmail.com>> escreveu: Apparently both IATA and Brazil's own airline industry (ABEAR) are pushing back on the government, citing at least three million passengers on 42 thousand flights will be affected. Also stated by ABEAR's representative (translated via Google Translate): "Short-term changes bring risks to the entire operation of airlines". It's good to see others have realized the risk. I worry about the back and forth though. https://www.panrotas.com.br/aviacao/aeroportos/2018/10/iata-ve-troca-no-horario-de-verao-com-profunda-preocupacao_159365.html https://www.panrotas.com.br/aviacao/empresas/2018/10/abear-se-posiciona-contra-a-mudanca-do-horario-de-verao_159323.html http://www.abear.com.br/imprensa/notas-e-releases/mostrar/posicionamento-abear-sobre-mudanca-do-horario-de-verao -Matt ________________________________ From: tz < tz-bounces@iana.org< mailto:tz-bounces@iana.org>> on behalf of Paul Eggert < eggert@cs.ucla.edu< mailto:eggert@cs.ucla.edu>> Sent: Thursday, October 4, 2018 8:37 AM To: F?bio Gomes Cc: Time Zone Mailing List Subject: Re: [tz] Another change on Brazilian DST time On 10/4/18 4:49 AM, F?bio Gomes wrote: > How long does it takes to update tzdata with this new information? It depends on what you consider an "update". I just now updated the development version < https://github.com/eggert/tz> with the attached patch, and you can use that now if you like. I'd like to plan for a new tzdb release soon after the presidential decree is published (please let me know when that happens). > we have a very shourt window to apply this new update. That's unfortunately true. We have a paragraph about this in < https://data.iana.org/time-zones/tz-link.html>. Here's how Google Translate renders it in Portuguese, and perhaps you can improve this translation and send it to Moreira Franco, the minister of Mines and Energy, who's supposed to be in charge of DST in Brazil: --- Se o seu governo planeja alterar seus limites de fuso hor?rio ou as regras de hor?rio de ver?o, informe < tz@iana.org< mailto:tz@iana.org>> com bastante anteced?ncia, pois isso coordenar? as atualiza??es para muitos telefones celulares, computadores e outros dispositivos em todo o mundo. Com menos de um ano de anteced?ncia, h? uma boa chance de que alguns rel?gios baseados em computador operem incorretamente ap?s a altera??o, devido a atrasos na propaga??o de atualiza??es de software e dados. Quanto mais curto for o aviso, mais prov?veis ser?o os problemas do rel?gio; veja "Sobre o tempo das mudan?as de fuso hor?rio" < https://codeofmatt.com/2016/04/23/on-the-timing-of-time-zone-changes/> para exemplos. -------------- next part -------------- An HTML attachment was scrubbed...

They are not a primary source for our purposes. Further, the change has already been made in the development version: https://github.com/eggert/tz/commit/efda0562d7fc7bc90b6cab76998fab8b4953e056 As Paul mentioned before, he is a volunteer, and there is no set timetable for full releases. https://mm.icann.org/pipermail/tz/2018-October/026937.html In particular, we are also waiting for a change in Volgograd, Russia to become official: https://mm.icann.org/pipermail/tz/2018-September/026898.html If you need updated data files for Brazil faster, source files for the bleeding-edge development version are available from https://github.com/eggert/tz in the meantime. Otherwise, please be patient. A lot of last-minute changes tend to happen at this time of year, so it is advantageous to batch them together when possible. -- Tim Parenti > -------------- next part -------------- An HTML attachment was scrubbed...

Not really, they are guessing against the same information as tz itself is and timeanddate.com is just as likely to be right as tz is ... That IATA is now complaining about the very short notice not being acceptable may be better at encouraging governments to provide adequate leadtimes on these sort of changes? -- Lester Caine - G8HFL ----------------------------- Contact - https://lsces.co.uk/wiki/?page=contact L.S.Caine Electronic Services - https://lsces.co.uk EnquirySolve - https://enquirysolve.com/ Model Engineers Digital Workshop - https://medw.co.uk Rainbow Digital Media - https://rainbowdigitalmedia.co.uk ------------------------------ Subject: Digest Footer _______________________________________________ tz mailing list tz@iana.org https://mm.icann.org/mailman/listinfo/tz ------------------------------ End of tz Digest, Vol 85, Issue 19 **********************************
