Kiev -> Kyiv
by Roman Dmytriv May 30, 2022

May 30, 2022

Hello IANA team! "After Ukraine's 1991 independence, the Ukrainian government introduced the national rules for transliteration of geographic names <https://en.wikipedia.org/wiki/Romanization_of_Ukrainian> into the Latin alphabet for legislative and official acts in October 1995,[23] <https://en.wikipedia.org/wiki/Name_of_Kyiv#cite_note-:1-23> according to which the Ukrainian name Київ is romanized <https://en.wikipedia.org/wiki/Romanization> as *Kyiv*. These rules are applied for place names and addresses, as well as personal names in passports, street signs, and so on." I know you are all busy, but you made a mistake in the timezone name. Just want to make a request to change "Kiev" to "Kyiv". I will be grateful for the answer. Thank you! Best regards, Roman Dmytriv tel: +380633709302

Change some timezone names
by gusak ivanov May 27, 2022

May 27, 2022

Good evening! I’ve read some great news, that you are finally changing Europe/Kiev to Europe/Kyiv. Can other Ukrainian timezones get the same treatment, and so get Europe/Uzhgorod to be changed to Europe/Uzhhorod and Europe/Zaporozhye to Europe/Zaporizhzhia? All according to the officially recognized UNGEGN World Geographical Names. Thanks

Duplicated shell commands on the tz-link.html IANA page
by Max Nikulin May 25, 2022

May 25, 2022

Hi, Some time ago I have noticed that shell commands are duplicated in the "Downloading the tz database" section on the following page https://data.iana.org/time-zones/tz-link.html#download > mkdir tzdb > cd tzdb > wget https://www.iana.org/time-zones/repository/tzcode-latest.tar.gz > wget https://www.iana.org/time-zones/repository/tzdata-latest.tar.gz > gzip -dc tzcode-latest.tar.gz | tar -xf - > gzip -dc tzdata-latest.tar.gz | tar -xf - I think it is better to remove some commands.

Unexpected last transition in Africa/Casablanca
by Almaz Mingaleev May 19, 2022

May 19, 2022

Hi Paul, Here are the last transitions in Africa/Casablanca output (rearguard format): transition,type,[UTC time],[Type offset],[Type isDST] 3672612000,1,2086-05-19T02:00:00Z,PT1H,DST 3699828000,2,2087-03-30T02:00:00Z,PT0S,STD 3703456800,3,2087-05-11T02:00:00Z,PT1H,STD So change is from standard to standard, even though offset changes from 0h to 1h. Is that expected behaviour? As Africa/El_Aaiun is using Morocco rules, its transitions are also affected. This affects 64-bit section only, 32-bit section looks fine to me. Thanks, Almaz Data above is output of debug tools used in Android. The way I've built data an byte manipulations if needed: mkdir /tmp/zic cd /tmp/zic git clone https://github.com/eggert/tz.git . make -C . zic make -C . NDATA= rearguard.zi mkdir data ./zic -b fat -d ./data rearguard.zi byte manipulations: Let's skip 32-bit header: xxd -seek 20 -c 4 -l 24 data/Africa/Casablanca typecnt: 94 timecnt: 5 charcnt: 12 32-bit block size = 94 * 4 + 94 + 5 * 6 + 12 = 512 64-bit start = 44 + 512 = 556 64-bit header: xxd -seek 576 -c 4 -l 24 data/Africa/Casablanca: timecnt: 196 typecnt: 4 <- 32-bit section has 5 charcnt: 12 transition types offset: 556 + 44 + 196 * 8 = 2168 xxd -seek 2168 -c 1 -l 196 data/Africa/Casablanca ... 00000934: 02 . 00000935: 01 . 00000936: 02 . 00000937: 01 . 00000938: 02 . 00000939: 01 . 0000093a: 02 . 0000093b: 03 . <- the last transition local time records offset = 556 + 44 + 196 * 9 = 2364 xxd -seek 2364 -c 6 -l 24 data/Africa/Casablanca 0000093c: ffff f8e4 0000 ...... 00000942: 0000 0e10 0104 ...... 00000948: 0000 0000 0008 ...... <- standard time 0000094e: 0000 0e10 0004 ...... <- also standard time

Change IANA time zone identifier for Kyiv to Europe/Kyiv.
by Luda Melnykova May 19, 2022

May 19, 2022

Hello, Hope this email finds you well. I would like to raise a request for a value change in TZ DB. I believe, that current IANA time zone identifier for Kyiv (Europe/K*ie*v) is not fully correct. Background of this request lies in a transliteration of a city name. *Kyiv* is derived from the Ukrainian language name Київ, while *Kiev* is derived from the Russian language name Киев) as the name of the Ukrainian capital. Kyiv is already in use in international lists for IATA, ICAO and other organizations, which follow the decision of the U.S. Board on Geographic Names. Kyiv, as a name of Ukrainian capital, is also mentioned on time.is site Kyiv: 19:42 (time.is) <https://time.is/Kyiv>. So, I believe, it is fully logical to follow latest guidelines and rename IANA time zone identifier as well. If you are interested to learn more about it, please check out this wiki article: KyivNotKiev - Wikipedia <https://en.wikipedia.org/wiki/KyivNotKiev> Please let me know if any questions or concerns. Many thanks. Regards, Liudmyla

Time in Russian occupied Ukraine
by alois＠astro.ch May 14, 2022

May 14, 2022

Does anyone know which time zone is used in the "separatist" or Russian occupied areas of eastern Ukraine? Or in the areas temporarily occupied during Russian invasion in the north of Kiev, from which Russia has withdrawn again? Until 27 March 2022, Ukraine was on 2h east, while western Russia was on 3h east (Europe/Moscow), like Crimea (Europe/Simferopol). Now since the begin of DST they have the same time offset.

2021e Asia/Dushanbe
by Nick Deguillaume May 14, 2022

May 14, 2022

Hello, I am currently developing a C++ time-zone database parser, building on top of Howard Hinnant's work. I am writing thorough checks. One Zone check that I am experimenting with is: *If the FORMAT field contains either a "%s" or a '/' then the RULES field must contain a named rule.* However line 3840 of the asia file in: https://data.iana.org/time-zones/releases/tzdata2021e.tar.gz fails this check, as highlighted in yellow in the table below. # Tajikistan # From Shanks & Pottenger. # Zone NAME STDOFF RULES FORMAT [UNTIL] Zone Asia/Dushanbe 04:35:12 - LMT 1924 May 2 5:00 - +05 1930 Jun 21 6:00 RussiaAsia +06/+07 1991 Mar 31 2:00s 5:00 1:00 +05/+06 1991 Sep 9 2:00s 05:00 - +05 My guess is that '+05/+06' should be '+05'. I may well be wrong. Could you let me know either way? If you are interested, I have found a few other bits and pieces where the data files are in slight variance with the documentation but are not show-stoppers. Most of these occur in the very early releases. (I am testing every database available on https://data.iana.org/time-zones/releases/) Regards Nick Deguillaume +44 75 2828 6473

Changes to timezone names
by Ростислав Салабай May 12, 2022

May 12, 2022

Good morning! Since Kyiv became an official spelling of the capital of Ukraine, few years have passed. And people more and more use the new spelling, instead of Kiev. That includes large and small news sites, posts of politicians and most social media feeds (seeing Kiev right now is much more rare than Kyiv). Even Wikipedia and Oxford English Dictionary have changed their spellings to Kyiv too, and large companies like Apple follow along. And actually, using Kiev causes more inconvenience for some people than Kyiv, in things that use tz database, as many are unable to find the right timezone (and this isn't something made up, I've seen lots of complains in forums and GitHub issue requests that Kyiv is missing or spelled wrong). Also, the outgoing war in Ukraine has sped up that process of switching Ukraine to Ukrainian-based things, and not Russian ones. So, in my opinion, it's the perfect time to finally ditch Kiev for good, and start using Kyiv (and so the Europe/Kyiv timezone) as the only name for that beautiful city. Rostyslav

Updates on Iranian Time Zone (IRDT)
by Mohammad Ali Tofighi May 11, 2022

May 11, 2022

Hi. Recently the Iranian parliament has decided to remove daylight saving from the Iranian time zone, eliminating the one-hour shift in the summer time. Hence, it is always going to be UTC+3:30. *This is not their final decision yet* and there is a final confirmation to be made, but I just wanted to inform you about the update to prepare possible modifications. I'm a software engineer and if we have the update on *tzdata* package as soon as possible, the software companies can adjust themselves accordingly. Please read these official news: https://www.isna.ir/news/1400122419045/ https://www.yjc.news/00Xw0k Regards, Ali Tofighi

Request to provide .tar.gz tarballs for tzdb
by Kim Davies May 6, 2022

May 6, 2022

Dear colleagues, We’ve been asked by this correspondent to forward this request on to this list. In response to the original request we explained the lzip distribution is largely an amalgam of the gzip distributions, and they indicated they still wanted gzip to be considered specifically to increase “availability for low end systems as lzip isn’t that widely supported”: Subject: Provide .tar.gz tarballs for tzdb Date: Mon, 2 May 2022 13:23:15 +0300 From: "Firas Khalil Khana" <firasuke(a)gmail.com> To: iana(a)iana.org Hey there, I've come to notice that both tzcode and tzdata have .tar.gz tarballs but tzdb only has .tar.lz (lzip) tarballs which isn't a commonly used format. Would it be possible to provide gzipped tarballs for tzdb as well? Thanks! -- Kim Davies VP, IANA Services, ICANN President, PTI
