Set up correct name to Zone Europe/Kyiv
by Alexey Furashev Oct. 31, 2016

Oct. 31, 2016

Hello All, In source file https://github.com/eggert/tz/blob/master/europe please change city name to correspondent standards ISO 3166-2:UA and UNGEGN. We have to write bug reports to software developers, because time zone entry names are incorrect. Incorrect name of time zone entries can't be used for our practical needs. ------------- str: 3663 from 'Zone Europe/Kiev' to 'Zone Europe/Kyiv' # ISO city code is UA-30 (https://www.iso.org/obp/ui/#iso:code:3166:UA ) ------------- str: 3691 from 'Zone Europe/Zaporozhye' to 'Zone Europe/Zaporizhzhia' ------------- Rules transliteraion from Ukranian to Latin see on site http://zakon4.rada.gov.ua/laws/show/55-2010-%D0%BF On-line service transliteration: https://dmsu.gov.ua/transliteration.html Oleksii.

EU Parliament debates DST
by Matt Johnson Oct. 28, 2016

Oct. 28, 2016

Yesterday there was an extensive debate in the European Union Parliament concerning daylight saving time. The recordings and text are available here: http://www.europarl.europa.eu/plenary/en/debate-details.html?date=20161027&… Expand the section titled: "15:04 - 16:05 Switch between summer and winter time (debate)" My favorite is the passionate argument made by Indrek Tarand, MEP from Estonia, at 15:34:21. Though I'm not sure his history is quite so accurate. ;-) Thanks to http://www.timeanddate.com/news/time/eu-debate-dst.html for the heads up. -Matt

Historical discrepancies for Italy.
by Pierpaolo Bernardi Oct. 27, 2016

Oct. 27, 2016

Hello, about Italian time, I see: # From Paul Eggert (2006-03-22): # For Italian DST we have three sources: Shanks & Pottenger, Whitman, and # F. Pollastri # Day-light Saving Time in Italy (2006-02-03) # http://toi.iriti.cnr.it/uk/ienitlt.html # ('FP' below), taken from an Italian National Electrotechnical Institute # publication. When the three sources disagree, guess who's right, as follows: I don't know about the other sources, but: - the url given to cnr.it is dead. - The authoritative source for time in Italy is the national metrological institute, which has a summary page of historical DST data at http://www.inrim.it/res/tf/ora_legale_i.shtml - Some of the data in TZ does not agree with this page. I think that there must be VERY strong evidence that the INRIM is wrong before preferring other sources? Cheers

Balearics: Institutional declaration in favor of keeping the summer time
by Martin Kaistra Oct. 25, 2016

Oct. 25, 2016

Hello, According to https://www.theguardian.com/world/2016/oct/24/happy-hour-balearics-try-to-k… the Balearic Parliament will ask the central government to stay on summer time. Even though I don't think that this is happening this year, it might still be of interest to you. Parliament website (in Catalan?): http://www.parlamentib.es/webdocs/NoticiaPIB.aspx?id=2031 martin

Crimea time zone name
by Ilya Dogolazky Oct. 23, 2016

Oct. 23, 2016

Hello! According to Wikipedia the biggest city of Crimea is not Simferopol (2014 population: 332,317 [1]), because Sevastopol is a larger one (2016 population: 418,987 [2]). According to "Crimea" article, Sevastopol indeed is the biggest city of Crimea [3]. Is there any reason why the Crimea zone name is Europe/Simferopol and there is neither Europe/Sevastopol zone nor a symlink. Cheers, Ilya D. [1] https://en.wikipedia.org/wiki/Simferopol [2] https://en.wikipedia.org/wiki/Sevastopol [3] https://en.wikipedia.org/wiki/Crimea
