Europe/Rome, 22 Sep 1866 rule
by Stephen Trainor May 7, 2019

May 7, 2019

In looking into Europe/Rome, I see there is the following rule: # Zone NAME GMTOFF RULES FORMAT [UNTIL] Zone Europe/Rome 0:49:56 - LMT 1866 Sep 22 (line 1660, europe, tzdb-2019a) In reading the page referenced in this 2016 thread on historical Italy time zones (https://mm.icann.org/pipermail/tz/2016-October/024363.html <https://mm.icann.org/pipermail/tz/2016-October/024363.html>), it states: "Regio Decreto del 22 Settembre 1866 n° 3224 di Re Vittorio Emanuele II ( in vigore dal 12 Dicembre 1866 ) Il servizio dei convogli nelle ferrovie, quello dei telegrafi, delle poste, delle messaggerie e dei piroscafi postali nelle Provincie Continentali del Regno d’Italia, verrà regolato col tempo medio di Roma a datare dal giorno in cui sarà attivato l’orario delle strade ferrate per la prossima stagione invernale 1866 – 1867.” (source: http://www.ac-ilsestante.it/MERIDIANE/ora_legale/ORA_LEGALE_ESTIVA_IN_ITALI… <http://www.ac-ilsestante.it/MERIDIANE/ora_legale/ORA_LEGALE_ESTIVA_IN_ITALI…>) This implies that the law went into effect on 12 December 1866, rather than the date of the decree (22 Sep 1866). This is further supported by this source: https://web.archive.org/web/20070824155341/http://www.iav.it/planetario/did… <https://web.archive.org/web/20070824155341/http://www.iav.it/planetario/did…>, which states: "In Italy in 1866 there were 6 railway times (Torino, Verona, Firenze, Roma, Napoli, Palermo). On that year it was decided to unify them, adopting the average time of Rome (even if this city was not yet part of the kingdom). On the 12th December 1866, on the starting of the winter time table, it took effect in the railways, the post office and the telegraph, not only for the internal service but also for the public. Moreover, without any particular law, but on a free initiative of the main Italian cities and as a consequence of the practical advantages of tying the railway time to the city time, and also for patriotic reasons ( Rome was not part of kingdom) it was decided to use the Rome time in public and private life producing thus a national time. Milano set the public watches on the Rome time on the same day (12th December 1866), Torino and Bologna on the 1st January 1867, Venezia the 1st May 1880 and the last city was Cagliari in 1886.” I wonder if the rule should be modified to 1866 Dec 12, instead of 1866 Sep 22?

Comments for Europe/Kiev
by Leon V May 3, 2019

May 3, 2019

Hi First of all, my apologies if I'm not doing the right thing by sending this suggestion to this email - I couldn't find a more relevant process in CONTRIBUTING for the amendment I suggest. I'd like to suggest to remove the following paragraph in europe file: # Anyway, none of the common English-language spellings (Kiev, Kyiv, Kieff, # Kijeff, Kijev, Kiyef, Kiyeff) do justice to the common pronunciation in # Ukrainian, namely [ˈkɪjiu̯] (IPA). This pronunciation has nothing like an # English "v" or "f", and instead trails off with what an English-speaker # would call a demure "oo" sound, and it would would be better anglicized as # "Kuiyu". Here's a sound file, if you would like to do as the Kuiyuvians do: # https://commons.wikimedia.org/wiki/File:Uk-Київ.ogg Reasons for that: 1. I don't see how it's relevant 2. There are multiple major mistakes in it: a. there are no other common spellings of Kyiv other than Kyiv and Kiev. Searching the Internet for all other suggested spellings can easily confirm it; b. [ˈkɪjiu̯] is absolutely not a valid transcription; c. neither Ukrainian nor Russian standards would suggest to use f at the end of the written word, although when pronounced it may sound somewhat reminiscient of f (depending on pronunciation); d. I don't believe there is an English speaker who would pronounce "Kuiyu" similar to what it's actually pronounced in either Russian or Ukrainian; e. the linked sound file is of low quality and seems to either have a second half of the last letter cut off or just pronounced by someone very drunk. It's not pronounced with "u" at the end neither in Ukrainian nor in Russian, not even close. About me: born in Russia, lived for 30 years in Kyiv, 4+ years in Sydney, Australia. Have been working with English speakers from pretty much all around the world for 15+ years. Kind regards Leon
