Re: [tz] [IANA #1173666] Time zone change - Yukon Canada

Good day. I work for the Government of Yukon in Canada. We are in the process of revising our definition of time to be permanently on UTC -7, no longer observing a twice-annual time change. I was on the hunt for authoritative standards related to time, and saw the IANA come up as caretaker of the time zone database, which appears to be relied on for software and systems. I am contacting you to see if there is any process beyond notification to making this adjustment in your TZ database, and perhaps to know if there are other agencies that should be aware of what Yukon is planning. From what I see now, TZ database names "America/Dawson", "America/Whitehorse" and "Canada/Yukon" would be affected by this change. Our regulation is not yet complete, so it is not law at this time and I am not looking for immediate change. We are aiming for finalization here by November 1, 2020. Hope to hear from you soon.

IANA hosts the Time Zone Database, but the database is managed by the Time Zone Coordinator in conjunction with a mailing list. You can find find mailing list information here: https://www.iana.org/time-zones This document should have or point to much of the information you're looking for: https://data.iana.org/time-zones/tz-link.html As is noted at the link above, "If your government plans to change its time zone boundaries or daylight saving rules, inform tz(a)iana.org well in advance, as this will coordinate updates to many cell phones, computers, and other devices around the world. With less than a year's notice there is a good chance that some computer-based clocks will operate incorrectly after the change, due to delays in propagating updates to software and data. The shorter the notice, the more likely clock problems will arise; see https://imsva91-ctp.trendmicro.com:443/wis/clicktime/v1/query?url=https%3a%… for examples."

looking for information about changing time zone
by Françoise Kerjouan Sept. 11, 2020

Sept. 11, 2020

Madam, Sir, Im living in New Caledonia; our local government is thinking about changing time zone (from UTC +11 to UTC +12). Could you please tell me how long a lead notice should be to be sure that the international community will get and process the information ? I understood that the ICAN TZ database is widely used, but I didnt catch if it is also used for international transports (by airports for example). Could you please tell me if it is the case? If not, whom should I ask for? Best regards, Françoise Kerjouan

Question] Regarding Asia/Yerevan timezone abbreviation
by Goun Lee Sept. 10, 2020

Sept. 10, 2020

Hi, I'm Goun from South Korea. I have a question regarding Asia/Yerevan timezone abbreviation When I checked the following line, https://github.com/eggert/tz/blob/master/asia#L127 it's written as 4:00 Armenia +04/+05 As far as I know, Armenia has no DST time, so the abbreviation should +04. isn't it? I'm just wondering if it's correct or not. best regards. Goun

timezone DB distribution
by Juergen Naeckel Sept. 8, 2020

Sept. 8, 2020

Hey there, First of all, I would like to thank you. I have to implement something in JavaScript that uses timezones. However, I am using an older JS version that does not have the flexibility like today’s JS. So I was looking for a repository holding all current timezones and rules for it, rather then me, checking time and again how which timezone is configured 😉 This really could help me. Reading through the files, it sometimes made me chuckle and I was actually surprised how fluent timezones are handled. Changes almost every year… I would like to recommend some improvements. I know you have pretty stable release by now. I am aware that changes probably to the structure might affect a lot of people/projects. However… First of all, a tar.gz is Linux specific. True, you could install additional Windows software. But, that might not go well with customers of mine. I think a ZIP would be acceptable for both worlds. Since I was interested in the repository, I downloaded the “Data only distribution”. I found six files containing the TZ information. And I found 27 files, containing other stuff. Well, there might be three or four files in a grey zone (calendars, backlist…). But I definitely do not consider MAKEFILE and .awk file as part of a “data only distribution”. Maybe move them to a separate folder in the GZ file? Finally, I got one more recommendation/question. I had read the readme file but it didn’t explain the data I saw in the files. It took me a while to understand the concept of the data structure. Some info of what to see in the file, and how to read it would help. And I think the first line of the ZONE definition contains some inconsistency (maybe I still didn’t understand it correctly). Below is a screenshot. See the first line for the zones? It looks mismatched with the New York. The RULE and the [UNTIL] are probably in the wrong column. Format is probably missing. [cid:image002.png@01D674A5.27F71B60] Then I noticed that the open-end validity. For rules it is denoted as “max” and for zones it is just a <blank>. Could we get some consistency here? And finally here comes my question: In the rules, I see in the column several times denoted with a tailing “u” or “s”. I think I read on one occasion that the times are denoted in “standard time”. I do not recall anymore where that was. But regardless, 1. I don’t understand what that “denoted in standard time” would mean 2. I definitely have no clue would the tailing “u”: would imply. [cid:image003.png@01D674A6.99550F50] Can you shed some light on this? Thank you! Not only for an answer but also for researching and compiling this list.

Iceland stays put on time zone
by Paul Eggert Sept. 7, 2020

Sept. 7, 2020

After more than two years of discussion, Iceland's government decided not to move its time zone back to -01, where it was before daylight saving time was introduced. Currently Iceland is at +00, effectively permanent DST. Proponents of changing back had argued that DST has harmful effects on human health. To counteract DST's health effects, the government decided instead to launch an educational campaign to get Icelanders to sleep more. It is also considering monitoring children's sleep habits and starting school days later. See: Gréta Sigríður Einarsdóttir, Iceland’s Time Zone to Remain Unchanged.
