Buggy %z behaviour in strftime
by Almaz Mingaleev 16 May '23

16 May '23

Attached code prints "+0000 America/Los_Angeles" both with glibc and with linked ToT strftime implementation. On MacOs it prints "-0800 America/Los_Angeles". Is it a known issue?

United States Senate reintroduced Sunshine Protection Act, enabling Permanent DST
by Phake Nick 14 Nov '22

14 Nov '22

I don't quite understand the legal text of the bill itself [2], but according to my reading, it seems like the bill will end DST across the entire US by shifting the standard time forward an hour, except in states/territories/area that currently doesn't enact DST, which they can choose to follow the new standard time or old standard time? 1: https://www.rubio.senate.gov/public/index.cfm/2021/3/rubio-colleagues-reint… 2: https://www.rubio.senate.gov/public/_cache/files/d34c77c0-acea-4074-bc57-14…

It's related to a portability problem you reported on MS-Windows in response to which in 2018d I committed a patch that introduced RESERVE_STD_EXT_IDS: https://github.com/eggert/tz/commit/24b45243c5210b4196987fdd06e6c288c358a268 When I recently added the randomish filename code to the development version, I neglected to deal with RESERVE_STD_EXT_IDS. The second attached patch should fix this issue. Please give the two patches a try, as I don't use MS-Windows and can't easily test these patches on that platform. > a test run of zdump -v produced way more output than in the last release, the Linux output seems to have become longer too, but maybe this is still under development. That change is intentional, and was caused by this: https://github.com/eggert/tz/commit/ac07b446a3afaa4cb1ae11a91785a201c91f6351 along with some neighboring commits. Thanks for reporting the problems, and I hope the current development version of tzdb addresses the issues you mentioned.

Moving more zones to 'backzone'
by Paul Eggert 29 Sep '22

29 Sep '22

Release 2021b moved to 'backzone' nine zones whose timestamps since 1970 were duplicates of other zones, as part of a process that started in 2013 in the interests of removing prior inequities, one step at a time. If we were to continue this process in the same way, we could install the attached proposed patch which would move more zones, chosen via the same procedure used for 2021b. It strikes me, though, now that Stephen Colebourne has established a mechanism that can let downstream users keep the duplicate-since-1970 zones, that it may be a more effective use of our time to move the rest of the duplicate-si ce-1970 zones now, while no urgent changes are pending. This would move another twelve zones if I've counted correctly, and would let us more efficiently turn our attention to other issues. Comments welcome.

Mexico may eliminate DST next year- except parts of some northern states
by wtz＠worldtimezone.com 01 Sep '22

01 Sep '22

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

Canonica and non-canonical timezone question
by Andriy Hromyak 30 Aug '22

30 Aug '22

Hello and good day I have posted a question about a problem I am dealing with here: https://github.com/moment/moment-timezone/issues/828#issuecomment-1228548097 could you please assist on providing info on how we can distinguish canonical and non-canonical timezones. Some services do not allow non-canonical timezones yet lib we use provide some time non-canonical ones. so we need way not to receive non-canonical timezones or have marker that we can know that and maybe you can provide the best racice way to map it to canonical. best regards -- Hromyak Andriy | Lead software developer andriy.hromyak(a)visiquate.com
