[tz-announce] 2018g release of tz code and data available
The 2018g release of the tz code and data is available. It reflects the following changes, which were either circulated on the tz mailing list or are relatively minor technical or administrative changes: Briefly: Morocco switches to permanent +01 on 2018-10-27. Changes to future timestamps Morocco switches from +00/+01 to permanent +01 effective 2018-10-27, so its clocks will not fall back on 2018-10-28 as previously scheduled. (Thanks to Mohamed Essedik Najd and Brian Inglis.) Changes to code When generating TZif files with leap seconds, zic no longer uses a format that trips up older 32-bit clients, fixing a bug introduced in 2018f. (Reported by Daniel Fischer.) Also, the zic workaround for QTBUG-53071 now also works for TZif files with leap seconds. The translator to rearguard format now rewrites the line "Rule Japan 1948 1951 - Sep Sat>=8 25:00 0 S" to "Rule Japan 1948 1951 - Sep Sun>=9 1:00 0 S". This caters to zic before 2007 and to Oracle TZUpdater 2.2.0 and earlier. (Reported by Christos Zoulas.) Changes to past time zone abbreviations Change HDT to HWT/HPT for WWII-era abbreviations in Hawaii. This reverts to 2011h, as the abbreviation change in 2011i was likely inadvertent. Changes to documentation tzfile.5 has new sections on interoperability issues.

No, the decree itself states that it takes effect on 2018-10-28, not on the day of its publication. Consequently, the Zone changes should also be corrected: + 0:00 Morocco +00/+01 2018 Oct 27 - 0:00 Morocco +00/+01 2018 Oct 28 03:00 This only affects the instant when the dst bit is set to 0, so it is not a serious error.

Thanks, I installed the attached patch for the next tzdb version. I vaguely recall reading that the decree would take effect yesterday, but I was mistaken. As you say, the error wasn't serious.
Hello all, Just a friendly reminder that you may get help from the A0 Time Zone Migration utilities to programatically get the diffs between tzdb releases, so you can check/correct your data once a new tzdb is installed in your systems. Documentation for this OSS project is at: https://a0.github.io/a0-tzmigration/ <https://a0.github.io/a0-tzmigration/> for ruby and javascript. Examples of latest changes from 2018e to 2018f for: - Europe/Volgograd https://a0.github.io/a0-tzmigration/demo/?ta=Europe%2FVolgograd&va=2018e&tb=... <https://a0.github.io/a0-tzmigration/demo/?ta=Europe/Volgograd&va=2018e&tb=Eu...> - Pacific/Fiji https://a0.github.io/a0-tzmigration/demo/?ta=Pacific%2FFiji&va=2018e&tb=Paci... <https://a0.github.io/a0-tzmigration/demo/?ta=Pacific/Fiji&va=2018e&tb=Pacifi...> - America/Santiago https://a0.github.io/a0-tzmigration/demo/?ta=America%2FSantiago&va=2018e&tb=... <https://a0.github.io/a0-tzmigration/demo/?ta=America/Santiago&va=2018e&tb=Am...> from 2018f to 2018g for: - Africa/Casablanca: https://a0.github.io/a0-tzmigration/demo/?ta=Africa%2FCasablanca&va=2018f&tb... <https://a0.github.io/a0-tzmigration/demo/?ta=Africa/Casablanca&va=2018f&tb=A...> Getting the same diff in code is as simple as the following: import { TZVersion } from 'a0-tzmigration-js' // calculate changes from America/Santiago 2018e to America/Santiago 2018f let version_a = new TZVersion('America/Santiago', '2018e') let version_b = new TZVersion('America/Santiago', '2018f') let changes = await version_a.changes(version_b) console.log(changes) HTH, — Aldrin.
