Italy April 1944 discrepancy between comment and data
by Alois Treindl 05 Oct '21

05 Oct '21

For Italy in 1944 zone Europe/Rome there is a discrepancy between the comment and the data. comment: # From Paul Eggert (2016-10-27): # Go with INRiM for DST rules, except as corrected by Inglis for 1944 # for the Kingdom of Italy. This is consistent with Renzo Baldini. # Model Rome's occupation by using C-Eur rules from 1943-09-10 # to 1944-06-04; although Rome was an open city during this period, it # was effectively controlled by Germany. Data for Italy is Rule Italy 1944 only - Apr 2 2:00s 1:00 S Data for C-Eur is: Rule C-Eur 1944 1945 - Apr Mon>=1 2:00s 1:00 S where Mon>=1 in 1944 is April 3. So Rome is NOT following C-Eur. I think the rule for Itay is right, only the comment is misleading.

Removing systemv, pacificnew, Rule TYPEs, zic -y
by Tim Parenti 04 Oct '20

04 Oct '20

I noticed recently that the systemv file, which adapted a subset of North American zones with limited rulesets to old versions of System V, has had all its once-useful bits commented out since 2005p. Looking back at list archives, even discussion at the time argued that the file wasn't really needed then. The attached proposed patch 0001 removes this obsolete file and its references. Of course, I was only looking at systemv in the first place because I'd also recalled that we're still distributing the pacificnew file, which has caused some confusion every so often and has likewise generally outlived its usefulness. This led me to the related file yearistype.sh, which is also unused, except as a default script to pass to the Makefile to process the TYPE field of Rule lines. Given that the TYPE field hasn't been used by tzdata since 2000f and has been more formally deprecated since 2015f, the whole unused feature is ripe for "spring cleaning". The attached proposed patch 0002 completely drops support for the TYPE field (marking it reserved for compatibility purposes) and causes non-trivial use of the field or use of zic's -y option to error (instead of warning as it has since 2017c). It also removes the pacificnew and yearistype.sh files that are no longer needed and updates documentation accordingly. I don't presently foresee any need to repurpose the nullified field down the road, but this is the next step in allowing us to "reclaim" it in the event that such a need should arise in the future. -- Tim Parenti

Updating zic.c to further match Link line field names
by Tim Parenti 03 Oct '20

03 Oct '20

In working on my latest proposed patch, I also noticed an outdated error message in zic.c which referred to the FROM field of a Link line. We had updated these field names in comments and documentation in release 2014g to be more descriptive and readily understandable like the parameters of 'ln': https://github.com/eggert/tz/commit/78e3924ea43079a0f3333677a728e0f0ed679cd3 The attached proposed patch further updates the zic.c code to more consistently use these new names throughout. This mostly affects the naming of parameters and locals, but a few macros and struct fields are also updated for consistency. -- Tim Parenti

Tim Parenti as backup TZ Coordinator?
by Paul Eggert 09 Jul '20

09 Jul '20

Tim Parenti's recent emails to the list reminded me that I'd long been meaning to nominate him to be my backup as TZ Coordinator. We should have a backup in case I am no longer available due to retirement or whatever, not that I'm planning to retire any time soon. I would like to start by giving him commit privileges to the development repository on GitHub, so that his contributions can become part of releases more easily. Tim has been a longtime and substantial contributor to tzdb, as evidenced by his detailed and careful patches. Although he's mostly worked in the tzdata area, he's also proficient on the code side, as his recent patch proposals demonstrate. He and I have corresponded by email about this and he's indicated his willingness to take on the responsibility. I'd appreciate reactions to Tim's offer to be backup; please respond within the next week.

The procedure is to send email to tz(a)iana.org with official citations, preferably with pointers to copies in English since the mailing list is in English. For best results, give one years' notice before the dates of change. For more details, please see: https://data.iana.org/time-zones/tz-link.html#changes

27 May '20

Hello, I was just reading the europe tz file and found a typo. The comment in the file gives the date 26/6/1900 but in fact it was July (7) not June (6). In the same text there is a reference to the official document of 26/7/1900. Attached you will find the patch.

we have used this code to get the IANA tz version. public static String getTimezoneDatabaseIANAVersion() { File readmeFile = new File(ZONEINFO_PATH, "README"); File alternativeReadmeFile = new File(ZONEINFO_PATH, "README.txt"); if (!readmeFile.exists()) { readmeFile = alternativeReadmeFile; } out read me.txt file contain generated by Gradle Based on http://www.iana.org/time-zones/repository/releases/tzdata2020a.tar.gz means we are using correct tzdata2020a.
