US DoT report on time zone impacts and uniformity
by Tim Parenti Sept. 23, 2022

Sept. 23, 2022

Time zones eking their way into popular media again… CNN reports tonight that officials at the US Department of Transportation are working on translating their official time zone boundaries (described in regulatory texts) into the form of an official map, after — gasp! — "investigators found no single map accurately showing the boundaries nationwide", along with several inconsistencies on their own websites. https://www.cnn.com/2022/09/22/politics/time-zone-map-transportation-depart… Of course, beneath the surface, this was just one finding from a 28-page report published by the DoT's Office of Inspector General on Tuesday: DOT Can Improve Processes for Evaluating the Impact of Time Zone Changes and Promoting Uniform Time Observance, 2022-09-20 https://www.oig.dot.gov/sites/default/files/DOT%20Time%20Zone%20Final%20Rep… Among the other major findings of the report are that DoT is "responsible for evaluating whether requests to change time zones serve the convenience of commerce," but lacks "written guidance for how…officials should validate the information provided by petitioners" when a time zone change is proposed, making it difficult to address the potential impacts associated with a change. The report recommended "evaluat[ing] the relevance of the convenience of commerce questions" developed to weigh such considerations, and updating the questions, if necessary, to "reflect modern commerce-related impacts of time zone changes". And while DoT finds it "has no role in DST exemptions, …it is responsible for fostering and promoting uniform time observance, including DST", but again lacks "processes for tracking or monitoring localities" whose observances deviate from those assigned. The absence of an "official repository of detailed maps" was found to be limiting the DoT's ability to monitor "non-uniform time observance" as well as the public's ability to identify it. A note in an appendix further points out that a portion of the official Central–Mountain time zone boundary through Stanley County, South Dakota (near Pierre) refers to a railway river crossing… and that the railway went out of business in 1995. -- Tim Parenti

Timezone name changes
by Ростислав Салабай Sept. 22, 2022

Sept. 22, 2022

Greetings! Due to the ongoing war in Ukraine, for a few months now, Ukrainian based transliterations of city names are getting more and more commonly used. Firstly, it started with Kyiv, and now other names follow along. Some names like Odessa or Kharkov are still more commonly using Russian transliterations, but two other cities, Uzhgorod and Zaporizhzhia, on tz timezone list, aren't like that. It can be seen online, for example, on social media or on platforms like Google Analytics. So, I think that it's time to change Europe/Zaporozhye to Europe/Zaporizhzhia and Europe/Uzhgorod to Europe/Uzhhorod. Of course, while leaving old timezone names as links to new ones, for fallback reasons

the text is correct and matches with the cabinet decision that is attached previously ,so kindly ignore the illustration we will correct the illustration in the announcement and send the link again but to keep time we confirm that the text is correct we hope the TZ release will be issued as soon as possible في الأحد, سبتمبر 04, 2022 17:53 EDT, Paul Eggert <eggert(a)cs.ucla.edu> كتب: On 9/4/22 06:00, Michael H Deckers wrote: > The illustration on that page makes it clear that the > Arabic text is probably meant to say > winter time starts with the value 2 am on Saturday 2022-10-29 > rather than > the switch to winter time occurs when summer time would > have assumed the value 2 am on Saturday 2022-10-29 > as it was wrongly interpreted in the proposed changes > to Rule Palestine. Ouch. My guess is just the opposite. That is, my guess is that the illustration[1] (attached) in [2] is wrong, and I guess that the text is correct. That is, I think the illustration should show the clock moving backward from 2am to 1am, not from 3am to 2am. Heba Hamad, can you please confirm which is correct here? The illustration or the text? The text matches the document you already sent us. Thanks. [1]: https://mtit.pna.ps/Content/imgs/news/-8585393378987544401IMG-20220903-WA00… [2]: https://mtit.pna.ps/Site/New/1453

Helllo, There is #STDOFF comment introduced for some of the tzdata in the middle of the rule. Causing parsing issue in tzdata to create correct utc and dst information.

Amsterdam timezone prior to 1937 incorrect?
by Loek Engels Sept. 6, 2022

Sept. 6, 2022

Hi, Between 2022a an b the timezone info for Europe/Amstedam is removed: Z Europe/Amsterdam 0:19:32 - LMT 1835 The timezone info for Brussels around that date differs from Amsterdams timezone info. Determining the timezone information for dates around that period on my Linux system in python returns since the latest update an offset of 0 minutes as opposed to the 19 minutes previously. Is the removal for this timezone information intentional or a bug? Regards, Loek

Mexico may eliminate DST next year- except parts of some northern states
by wtz＠worldtimezone.com Sept. 2, 2022

Sept. 2, 2022

According to some news published on Wednesday, July 6, 2022 Mexico may eliminate DST next year- except parts of some northern states. "AMLO sends bill to eliminate daylight saving; Mexico to return to 'God's time'" https://mexiconewsdaily.com/news/amlo-sends-bill-to-eliminate-daylight-savi… https://www.reuters.com/world/americas/mexico-president-presents-bill-elimi… "Mexico president presents bill to eliminate daylight saving time" "It's likely that the clocks won't change next year in most states" "The bill only requires a simple majority to pass the federal legislature, meaning that it is likely to become law. With the support of its allies, the ruling Morena party commands a majority in both the lower and upper houses. Energy Minister Rocío Nahle and Health Minister Jorge Alcocer appeared at the president's morning press conference on Tuesday to present arguments in favor of getting rid of the twice-a-year time change...... ..................... However, God's clock and health worries may not apply in parts of some northern states where clock changes have been synchronized with states in the southern U.S. to facilitate cross-border trade and other connections. Energy Minister Nahle said on Tuesday that there would continue to be exceptions in some northern border municipalities." Regards, WorldTimeZone.com team
