Wrong timezone
by Minu Shie March 14, 2023

March 14, 2023

Hi, I've checked the sites that are currently using your database and all of them have the wrong timezone for Valle Hermoso, Tamaulipas, México. Which should be the same as Matamoros, Tamaulipas, México. (America/Matamoros) instead of (America/Monterrey).

Building tz with gcc-13
by Martin Jansa March 13, 2023

March 13, 2023

Hello, I was building tz with gcc-13 and noticed that without explicit -std=c2x it fails to build 2022g version with: ``` zic.c:462:1: warning: ‘noreturn’ attribute ignored [-Wattributes] 462 | static ATTRIBUTE_NORETURN void | ^~~~~~ zic.c:462:27: error: expected identifier or ‘(’ before ‘void’ 462 | static ATTRIBUTE_NORETURN void | ^~~~ ``` The last code change on github in this are was: https://github.com/eggert/tz/commit/dbfcefe0c129e36e8c5acbcedf1400c1b486d962 It builds fine for me with gcc-12 without -std: ``` __STDC_VERSION__ = 201710 __has_c_attribute(noreturn) = 0 ``` and with -std=c2x: ``` __STDC_VERSION__ = 202000 __has_c_attribute(noreturn) = 0 __STRICT_ANSI__ ``` but with gcc-13 it builds only with explicit -std=c2x: ``` __STDC_VERSION__ = 202000 __has_c_attribute(noreturn) = 202202 __STRICT_ANSI__ ``` Maybe because __has_c_attribute(noreturn) returns 202202 even when __STDC_VERSION__ doesn't accept it yet? ``` __STDC_VERSION__ = 201710 __has_c_attribute(noreturn) = 202202 ``` >From https://www.open-std.org/jtc1/sc22/wg14/www/docs/n2764.pdf it's not clear to me when exactly [[noreturn]] can be used. It says only this about the value `Drafting note: The value used for __has_c_attribute is a placeholder that is to be replaced by the editors with the year and month the proposal is accepted into the working draft.` Is it a bug in gcc or should it be handled somehow by private.h? Thanks

two distinct limits on time zone abbreviation length in tzcode?
by Paul Eggert March 13, 2023

March 13, 2023

I just noticed that tzcode has two distinct limits on time zone abbreviation length. One is MY_TZNAME_MAX (which is 255 on GNU/Linux and I expect smaller on other platforms); the other is TZ_ABBR_MAX_LEN (which is always 16). The latter limit was introduced in 2005, here: https://mm.icann.org/pipermail/tz/2005-May/013037.html These two distinct limits can lead to confusing behavior. For example, on GNU/Linux if you compile and build tzcode date you can see this behavior: $ TZ=ABCDEFGHIJKLMNOPQ4 date Sun Mar 5 07:21:41 ABCDEFGHIJKLMNOP 2023 $ TZ=AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA4 date Sun Mar 5 11:22:05 UTC 2023 In the first example, the "Q" is silently dropped (it's one more than the 16-byte limit), whereas in the second example, the entire TZ string is ignored and UTC is silently substituted. I'm thinking of changing the code so that there's just one limit, presumably the higher one, so that we don't get the confusing behavior noted above. Comments welcome.

Leap hour smearing...

...on an outdoor clock in my home town of Takoma Park, Maryland. The clock has a weird intermittent-sweep minute hand. It took about eight minutes to get from 2:00 to 3:08. @dashdashado https://youtu.be/XeVLyyBSOT8
