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

Canonica and non-canonical timezone question

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

Re: [tz] No time zone on Solaris servers

Aug. 26, 2022

On 8/26/22 10:06, W CUI wrote: > We are running 64-bit Solaris as showing from the "isainfo -v" output. Fine, but Solaris 10 /usr/bin/date is a 32-bit executable and is dynamically linked to a 32-bit C library /lib/libc.so.1 that is reading your TZif files. Presumably your "isainfo -v" outputs something like this: 64-bit sparcv9 applications vis2 vis 32-bit sparc applications vis2 vis v8plus div32 mul32 and the last two lines are what matter here. I expect that 64-bit Solaris 10 apps don't have this problem. To find out whether I'm right, you can run '/usr/bin/sparcv9/ls -l' on a new file and look at the resulting timestamp. Regardless, if this issue is a real problem for you then it's time to file a bug report with Oracle (you can tell them I sent you :-). And in the meantime you can get by with 'zic -b fat'.

No time zone on Solaris servers
by W CUI Aug. 25, 2022

Aug. 25, 2022

Hi list, We downloaded tzdb2022c and compiled it on a Solaris 10 server with TOPDIR=/newtz and other default config parameters. After compiling is finished, the zoneinfo directory is copied to an other Solaris server, then the date command does not show any time zone on the host. It seems the server is at UTC time zone. Can anybody point me on how to fix it? Thank you very much! Wei Sent from Yahoo Mail for iPhone

Add option to act like global-tz
by Paul Eggert Aug. 18, 2022

Aug. 18, 2022

I wangled a bit of free time and wrote the attached proposed patch, which adds an option that causes 'make install' to generate time zone data (TZif files) that are byte-for-byte identical to what Stephen Colebourne's global-tz currently generates. This is done via a few lines of awk script. The idea is to give an option to distros that prefer a separate Zone per ISO 3166 country, just as we already have build-time options for rearguard/vanguard form, TZif truncation, leap seconds, etc. I haven't installed this in the development database. Comments welcome as usual.

time_t truncation occurrence in tzcode

I suspect that you're talking about ICU's files concerning time zones as opposed to the tzdata files themselves, as the repository you mention stopped mirroring tzdata files after tzdata 2011k. ICU is downstream from tzdata and an ICU forum would be a good place to ask about ICU's status. A request for ICU to update to match tzdata 2022b (and 2022c) is here: https://unicode-org.atlassian.net/browse/ICU-22118 and I expect you can monitor and/or comment there.

[tz-announce] 2022c release of tz code and data available
by Paul Eggert via tz-announce Aug. 16, 2022

Aug. 16, 2022

The 2022c release of the tz code and data is available. This release reflects the following changes, which do not affect timestamps unless your system has the awk bug mentioned below: Briefly: Work around awk bug in FreeBSD, macOS, etc. Improve tzselect on intercontinental Zones. Changes to code Work around a bug in onetrueawk that broke commands like 'make traditional_tarballs' on FreeBSD, macOS, etc. (Problem reported by Deborah Goldsmith.) Add code to tzselect that uses experimental structured comments in zone1970.tab to clarify whether Zones like Africa/Abidjan and Europe/Istanbul cross continent or ocean boundaries. (Inspired by a problem reported by Peter Krefting.) Fix bug with 'zic -d /a/b/c' when /a is unwritable but the directory /a/b already exists. Remove zoneinfo2tdf.pl, as it was unused and triggered false malware alarms on some email servers. Here are links to the release files: https://www.iana.org/time-zones/repository/releases/tzcode2022c.tar.gz https://www.iana.org/time-zones/repository/releases/tzdata2022c.tar.gz https://www.iana.org/time-zones/repository/releases/tzdb-2022c.tar.lz The following convenience links are also available, although they may point to the previous release until the relevant caches are refreshed: https://www.iana.org/time-zones/repository/tzcode-latest.tar.gz https://www.iana.org/time-zones/repository/tzdata-latest.tar.gz https://www.iana.org/time-zones/repository/tzdb-latest.tar.lz Links are also available via plain HTTP, and via FTP from ftp://ftp.iana.org/tz/releases with the same basenames as above.

If your tzdata parser does not yet support negative DST offsets or times past 24:00, or if it insists on a 'pacificnew' file that is no longer present, this release's data entries can be turned into a rearguard-format tarball that should work even with these older parsers. This is intended to be a temporary transition aid for these parsers. To generate a rearguard-format tarball, obtain the full distribution as described above, and run the command 'make DATAFORM=rearguard tailored_tarballs' on a development host. Or you can run 'make rearguard.zi' to generate a single file that can be fed directly to a parser that works like 'zic'.

Re: [tz] Trivial questions about Tz

Thanks Paul It is theoretically possible that such a triple midnight could happen, but I assume it could happen only if some goverment/administration had poorly chosen their walltime transition times. ----- Original Message ----- From: Paul Eggert [mailto:eggert@cs.ucla.edu] To: "dpatte" <dpatte(a)relativedata.com> Cc: tz(a)iana.org Sent: Mon, 15 Aug 2022 15:46:55 -0700 Subject: Re: [tz] Trivial questions about Tz On 8/15/22 14:23, dpatte via tz wrote: > Are there any known cases in the tz database where two close offset and save changes in one region cause wall times in that region to have not just one but two repeats of the original wall times, such as 3 midnights with the same date?

The following shell command: zdump -i $(awk '/^Zone/{print $2}' main.zi) | awk 'o!="" && $3!="" && o!=$3 {print o, $3} {o = $3}' | sort -u prints output that should help answer your question. Each line of output is a distinct pair of (before, after) %z-style abbreviations that is observed somewhere in tzdb. I get 579 lines of output with current tzdb.

Trivial questions about Tz
by dpatte Aug. 15, 2022

Aug. 15, 2022

I was just curious... Generally, when a region comes off Daylight/Summer time, the wall time is set back, causing a wall clock to repeat a portion of wall times (albeit with a different time abbreviation). Likewise, if a region elects a new GMT offset that is further west than before, the wall time is also set back, also causing a repeat of wall times (again with a different time abbreviation). Are there any known cases in the tz database where two close offset and save changes in one region cause wall times in that region to have not just one but two repeats of the original wall times, such as 3 midnights with the same date? I am also curious what the largest single change to a save-time is in the database, and the largest single change to a GMT offset-time (though I assume the answer to this second one is Western Samoa).

make traditional_tarballs fails on macOS for 2022b

Aug. 15, 2022

This is a regression from 2022a. This is on macOS 13.0 but I suspect it will fail the same way on macOS 12. Also note that macOS does not have nroff installed, but that doesn’t look like a fatal error.

Time in Eucla (Western Australia)
by Robert Elz Aug. 13, 2022

Aug. 13, 2022

A friend has relatives driving towards Perth (from eastern AU). They sent him the attached photo (after I asked if they could confirm the time there as they passed through) from the local motel entrance. This is just a confirmation of what we already knew. Photo date is 13 August 2022; since it is a photo of clocks, the time is self evident (note, daylight, not near midnight). kre

Chile Timezone change
by Juan Luis Orellana Aug. 11, 2022

Aug. 11, 2022

Dear IANA Team, I'm glad I can be in touch with you, this mail has as objective, to ask for a tzdata update package, our Chilean Goverment changed the timezone change date from 09/03/23:59 to 09/10 23:59 (America/Santiago), due to political reasons. Please if you can answer me or guide me to make that change on the files, I'll apretitate that I'm struggling to correct that across from more than a thousand servers. I'll be in touch. Kind regards.
