Antarctica/McMurdo
by Wolfgang Pausch Oct. 16, 2013

Oct. 16, 2013

Hello, in my application, I used Antarctica/McMurdo in some test case. In version 2013d, file antarctica contained an entry # # # McMurdo, Ross Island, since 1955-12 # Zone NAME GMTOFF RULES FORMAT [UNTIL] Zone Antarctica/McMurdo 0 - zzz 1956 12:00 NZAQ NZ%sT which is gone in version 2013g. However, McMurdo is still referenced both in australasia in a link, and in the zone.tab file: ~/tmp/tzdata$ grep McMurdo * antarctica:# "in the US Camp (East Camp) we have been on New Zealand (McMurdo) antarctica:# McMurdo Station, Ross Island, since 1955-12 antarctica:# as supplies for the station were coming from McMurdo Sound, antarctica:# We use the same time as McMurdo does. antarctica:# See 'australasia' for Antarctica/McMurdo. australasia:Link Pacific/Auckland Antarctica/McMurdo zone.tab:AQ -7750+16636 Antarctica/McMurdo McMurdo, South Pole, Scott (New Zealand time) ~/tmp/tzdata$ I guess this is a inconsistency in the tzdata files...?

Hi Paul, thanks for referencing this, I hadn't spotted it until now. I assume Mike Douglass and Cyrus Daboo subscribe to this list? Great work - at first read the only thought I had was that JSONP should be supported.

[PATCH 0/4] Make tzselect more portable
by Patrick 'P. J.' McDermott Oct. 6, 2013

Oct. 6, 2013

These patches allow tzselect to run on almost any Bourne-compatible shell (tested: bash, BusyBox ash, dash, ksh93, mksh, pdksh, posh, yash, and zsh) and fix an issue with older versions of BusyBox awk (and makes the setting of FS more consistent throughout tzselect). The prompts are identical to those printed by ksh or bash, except that the final prompt now gives a more generic error message than the old "Please enter 1 for Yes, or 2 for No." message. I hereby disclaim copyright interest in these changes. -- Patrick "P. J." McDermott http://www.pehjota.net/ Lead Developer, ProteanOS http://www.proteanos.com/

Morocco not ending DST tonight - instead extending by one month
by Steffen Thorsen Oct. 4, 2013

Oct. 4, 2013

Morocco extends DST by one month, on very short notice, just 1 day before it was going to end. There is a new decree (2.13.781) for this, where DST from now on goes from last Sunday of March at 02:00 to last Sunday of October at 03:00, similar to EU rules. Official source (French): http://www.maroc.gov.ma/fr/actualites/lhoraire-dete-gmt1-maintenu-jusquau-2… Another source (specifying the time for start and end in the decree): http://www.lemag.ma/Heure-d-ete-au-Maroc-jusqu-au-27-octobre_a75620.html Our brief summary in English: http://www.timeanddate.com/news/time/morocco-ends-dst-2013.html Best regards, Steffen Thorsen - timeanddate.com

Cellphone tz updates often not happening in Israel
by Paul Eggert Oct. 3, 2013

Oct. 3, 2013

A couple of weeks ago there were widespread reports of problems in the tz database's updates getting propagated to end users in Israel. Many cellphones running Android, BlackBerry, iOS, and Symbian were still based on tz release 2012g or earlier, i.e., they had not updated even to tz release 2012h (2012-10-26), much less to the current rules for Israel as per tz release 2013d (2013-07-05). Hundreds of thousands of cellphones were reportedly affected by the problem, and some cellphone companies worked around the problem by advising their users to switch to Athens time. Unfortunately, Europe/Athens is also incorrect for Israel, as it gets the transition wrong by two hours this fall and by 49 hours next spring. And even if users were advised to switch back to Asia/Jerusalem after next month I wouldn't be surprised if some users forget, and run into a similar problem in March. I wonder why the cellphones' copies of the tz database are not being updated? My sources: Elis N. Israel does the time warp; daylight savings glitch wreaks havoc.

Re: [tz] Minor build fixes (#3)
by Paul Eggert Oct. 2, 2013

Oct. 2, 2013

Thanks, I pushed the following slightly-more-ambitious patch, which I think addresses all the issues you raised. >From 1d67c5bfca504b728bd7dd22d19128721196e20e Mon Sep 17 00:00:00 2001 From: Paul Eggert <eggert(a)cs.ucla.edu> Date: Wed, 2 Oct 2013 10:48:46 -0700 Subject: [PATCH] build: Makefile fixes; let user give AR and RANLIB; local libtz.a * Makefile: Let the user override AR, and build libtz.a before installing it, as suggested by Michael Forney in <https://github.com/eggert/tz/pull/3>. Also, let the user override RANLIB. Modernize a bit by assuming POSIX.2-1992 or later; this is safe nowadays and simplifies the libtz.a business. And treat 'leapseconds' more like we used to, since it's machine-independent a 'make clean' doesn't need to remove it. (TZLIB): Remove. (AR, RANLIB): New macros. (TABDATA): Add leapseconds, so that 'make' builds it by default. (DATA): Remove leapseconds, since $(TABDATA) now has it. (all): Depend on libtz.a, not $(LIBOBJS). (install): Install libtz.a using 'cp', like other files. Also invoke $(RANLIB) on it, after installing. Do not assume that TZDIR is not overridden. (install, INSTALL, check_time_t_alternatives): Use 'mkdir -p', as it's safe to assume nowadays (standardized in POSIX.2-1992). (install, INSTALL): Prefer 'cp -f' to 'rm' followed by 'cp', as it's safe to assume 'cp -f' nowadays (also standardized in POSIX.2-1992). (libtz.a): Rename from $(DESTDIR)$(TZLIB), since we now build it here. Use $(AR) rather than ar. Use $(RANLIB) rather than trying to guess it. (clean_misc): Do not remove 'leapseconds', as it's machine-independent. (maintainer-clean): Remove 'leapseconds' here instead. (clean, check_public): Standardize on 'rm -fr' rather than 'rm -f -r'; formerly the makefile was inconsistent. (set-timestamps.out): Don't ignore failurs of the actual touch command. --- Makefile | 92 ++++++++++++++++++++++++++++++---------------------------------- 1 file changed, 43 insertions(+), 49 deletions(-) diff --git a/Makefile b/Makefile index 1f83dde..74923e7 100644 --- a/Makefile +++ b/Makefile @@ -72,7 +72,6 @@ MANDIR= $(TOPDIR)/man # Library functions are put in an archive in LIBDIR.
