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.

'Australia/Canberra' time zone?
by John Pye 24 Apr '20

24 Apr '20

Hi there I have been a bit surprised that the TZDATA database lacks a listing for "Australia/Canberra", population 350,000. What is the basis for deciding which cities are included or excluded from the database? Does being the national capital, and the major city in its own state/territory warrant inclusion, or is there another criterion? Here is what I believe to be an official source about the Canberra timezone (at least for the present day): https://www.australia.gov.au/about-australia/facts-and-figures/time-zones-a… Cheers JP

incorrect timezone info from tar files

Hello, I'd like to report your downloads for the following Time Zones from this URL on your site are out of date: https://www.iana.org/time-zones For instance Europe/Istanbul moved to UTC 3 permanently in September of 2016 and no longer follow DST. I will place the correct times first, and then the incorrect IANA times second. Highlighted in orange have the incorrect time zone information (0 means there is no DST, 1 means they follow DST) TimeZone UTC Offset ObservesDST IANA_UTC_offset: IANA_ObservesDST: America/Campo_Grande -4 0 -4 1 America/Sao_Paulo -3 0 -3 1 America/St_Johns -3.5 1 -3 1 Asia/Sakhalin 11 0 10 0 Australia/Adelaide 9.5 1 9 1 Australia/Darwin 9.5 0 9 0 Australia/Lord_Howe 10.5 1 10 1 Europe/Istanbul 3 0 2 1 Indian/Cocos 6.5 0 6 0 Pacific/Chatham 12.75 1 12 1 Thanks.

Ping. Please fix the time zones of Ukraine. Or at least reply me. пт, 27 сент. 2019 г. в 20:21, Mikhail Gribanov <mikhail.gribanov(a)gmail.com>: > > Hi.

by Santos, Cosme 03 Dec '19

Hi, I am from brazil and I am trying to fix na issue with java, We used the command Execute C:\Program Files\Java\jdk1.8.0_161\bin>java -jar tzupdater.jar -v -f -l file:c:\temp\tzdata2019c-rearguard.tar.gz (via cmd) And restarted all the Java application, however, some parts of the application are with the correct time, others are not. I have found this link and I am trying to get a fix for this, but I'd like to as for ehlp. What is tzcode and tzdb, should I update them to? Also, the Brazil Timezone change, 2019 we won't have it, so a friend sent me the tzdata2019c-rearguard.tar.gz (is this a good file?)

USG_COMPAT and POSIX and XOPEN macros
by Andras Farkas 02 Dec '19

02 Dec '19

I've noticed that USG_COMPAT shouldn't be replaced by XOPEN macros since it's clear USG_COMPAT is meant to be something users of tzcode can toggle. However, if someone has an application where they set _XOPEN_SOURCE to 700 or another value, I wonder if there should be something equivalent to the following in private.h #ifndef USG_COMPAT # ifndef _XOPEN_VERSION # define USG_COMPAT 0 # else # define USG_COMPAT 1 # endif #endif But using _XOPEN_SOURCE instead. (while also retaining the block of code using _XOPEN_VERSION too. I think in cases where both macros are involved, priority should be given to _XOPEN_SOURCE since it's explicitly what an application programmer has asked for) Right now, the code only reads _XOPEN_VERSION (from the OS) but not _XOPEN_SOURCE (from the application) This possibly could also apply to how only _POSIX_VERSION is currently used, but not _POSIX_C_SOURCE (nor the obsolete _POSIX_SOURCE, but that's been superseded for a long time now) This topic originates in this thread: http://mm.icann.org/pipermail/tz/2019-November/028596.html http://mm.icann.org/pipermail/tz/2019-November/thread.html

Having read a bit on the United States Board on Geographic Names... https://en.wikipedia.org/wiki/United_States_Board_on_Geographic_Names <https://en.m.wikipedia.org/wiki/United_States_Board_on_Geographic_Names> ...and their best known actions (the renaming of Cape Canaveral to Cape Kennedy and back)... https://www.straightdope.com/columns/read/613/why-did-they-change-the-name-… ...I'm of two minds on the wisdom of having a Board of Time Zone Names.-S @dashdashado

Question about bug seen in OpenBSD and FreeBSD related to tzname
by Andras Farkas 23 Nov '19

23 Nov '19

Hello! Earlier this month, I noticed bugs in OpenBSD and FreeBSD related to tzname's values. https://marc.info/?l=openbsd-bugs&m=157379849727998&w=2 https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=241978 I noticed that both those OSes share relevant code with tzcode. How would I best test this stuff out with a recent release of tzcode? (i.e. how to make sure I'm including headers only from the 2019c tarball and not from my OS, when possible)

FreeBSD and USG_COMPAT
by Andras Farkas 23 Nov '19

23 Nov '19

FreeBSD doesn't support the int daylight or long timezone in time.h itself. tzcode supports them on OSes which already support them, like OpenBSD. I'm trying to figure out if it should be possible to compile tzcode to support daylight and timezone even on OSes which don't support them. I've saved the output of make (both stdout and stderr) when CFLAGS is set to -DUSG_COMPAT=1 alone into usgcompat.txt I've saved the output of make (both stdout and stderr) when CFLAGS is set to '-DUSG_COMPAT=1 -DHAVE_POSIX_DECLS=0' into both.txt What I'm seeing is that the OS's time.h is being included, under both configurations.
