Re: [tz] Time zone confusion in Morocco
by Hicham Boushaba Nov. 2, 2018

Nov. 2, 2018

We Moroccans didn't know about the change also before Friday, our government didn't take the time to neither study nor discuss the matter with us. And the real issue, is that Android devices (maybe iOS devices, I'm not sure) update the tzdb only via a system upgrade/patch, and we know that Android OEMs rarely update their devices, so Moroccans will stay impacted for a long time, and non-tech people don't have the necessary skills to change the timezone manually.

Will Morocco switch from +01 to +00 during Ramadan next year?

Thanks for the info. I installed the attached patches into the development version on GitHub to implement this. This patch doesn't exactly agree with the dates you specified (for 2019 it guesses falling back Sunday, May 5 and springing forward Sunday, June 9), but these dates are approximate until an official announcement and a methodical guess is better than no guess at all. Java users, please note that this patch uses negative DST in the main and vanguard formats; in rearguard format Morocco stays in the +00 timezone (instead of moving to +01 last weekend) and observes positive DST in every month but Ramadan.

Time zone confusion in Morocco
by Paul Eggert Nov. 1, 2018

Nov. 1, 2018

Since 2012 Morocco has been switching from +01 (DST) to +00 (standard time) for Ramadan. In an article in today's Morocco World News, Safaa Kasraoui implies (but does not explicitly state) that Morocco will continue this practice even after its time zone switch last weekend from +00 to +01, and thus that Morocco will switch from +01 (standard time) to +00 (presumably DST) during Ramadan next year. If so, we'll have to change tzdb again, this would be another use of negative DST, and I'll bring back my Emacs-based predictions of Ramadan for Morocco. Kasraoui also reports that MP Abdellatif Ouahbi has called on the Moroccan government to release the study that the government said it had conducted on time change. My guess is that no real study was conducted, that the government knew the change would be controversial, and that it announced the change with so little notice because it didn't want controversy to derail the change. The government's main argument for not using DST was the confusion and "tensions and diseases" of switchover, and its main argument for adopting +01 instead of +00 appears to be to smooth out peaks in electricity consumption, though it appears that there is no data to support either argument. As part of the time zone change, the government also changed school timetables so that schools will start at 09:00 instead of 08:00, effectively canceling the time zone change for schools. It said it will make further measures regarding DST, without giving details. Kasraoui reports, "Clocks set by the internet with Moroccan cities selected as the time zone returned to GMT on Sunday and, as of Wednesday, are still showing the wrong time." Presumably this mostly refers to Android and iOS phones; although my US-baseed Android 9 phone is not updated, the Ubuntu desktop that I'm typing this message on is updated. Ubuntu is downstream from Debian which in turn is downstream from tzdb, and the timeline for my desktop update was as follows (all times UTC): 2018-10-27 05:22:45 2018g timestamped 2018-10-27 05:23:38 2018g committed to development version 2018-10-27 12:10:11 2018g available from iana.org 2018-10-27 13:14:23 2018g created for Debian sid 2018-10-27 15:55:08 2018g announced on tz-announce(a)iana.org 2018-10-28 02:00:00 rule change takes effect in Morocco 2018-10-28 21:51:08 2018g created for Ubuntu bionic 2018-10-30 05:23:27 2018g updated on my desktop The update on my desktop was part of routine maintenance. Although Ubuntu is about as good as it gets in this area for a consumer-facing OS, we should be able to even better. Debian beat the deadline but Ubuntu (downstream from Debian) did not, my desktop had the wrong Morocco time for over two days, and my guess is that almost all cell phones and computers in Morocco still have the wrong data for Morocco.

zdump bug?
by Matt Johnson Oct. 29, 2018

Oct. 29, 2018

I notice when I run zdump like this: zdump /usr/share/zoneinfo/America/New_York The output is normal: America/New_York Sun Oct 28 18:23:35 2018 EDT But if I change to the America directory... cd /usr/share/zoneinfo/America zdump ./New_York The output is missing the abbreviation: ./New_York Sun Oct 28 22:23:48 2018 Is this expected? Seems like a subtle bug to me. The abbreviations are also missing with -v output. (Ran on Ubuntu Linux 16.04.5 LTS) Thanks, Matt

[tz-announce] 2018g release of tz code and data available
by Paul Eggert Oct. 29, 2018

Oct. 29, 2018

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. Here are links to the release files: https://www.iana.org/time-zones/repository/releases/tzcode2018g.tar.gz https://www.iana.org/time-zones/repository/releases/tzdata2018g.tar.gz https://www.iana.org/time-zones/repository/releases/tzdb-2018g.tar.lz As usual, links to the latest release files are here: https://www.iana.org/time-zones/repository/tzcode-latest.tar.gz https://www.iana.org/time-zones/repository/tzdata-latest.tar.gz https://www.iana.org/time-zones/repository/tzdb-latest.tar.lz Links are also available via plain HTTP, and via FTP from ftp://ftp.iana.org/tz/releases with the same basenames as above.

[PATCH] Support building zic.exe and zdump.exe natively on Windows with Visual Studio nmake.
by Manuela Friedrich Oct. 28, 2018

Oct. 28, 2018

Provide getopt() implementation for Windows as per ftp://ftp.es.ele.tue.nl/pub/users/jos/poster/getopt.c In localtime.c use native localtime(), gmtime(), ctime() and mktime(). Also use int or __int64 respectively for ssize_t type and check for Windows drive letters in tzloadbody(). In private.h and zdump.c define strotimax depending on Visual Studio version. It needs to be strtol for up to VS 2010 and stroll for higher versions. In zdump.c need prototype for gmtime_r() to suffice return type requirements. Also use __time64_t variables on Windows instead of time_t. In main() variable declarations had to be moved to the top to avoid compile errors. In zic.c dolink() need to have an extra mkdirs() call for Windows as we don't have link support here and the previous mkdirs() calls wouldn't have been called therefore. Also itsdir() needs separate Windows part to check for directory flag as the namesslashdot Linux alternative alway returns directory on Windows. Add nmake specific Makefile.nmake based on existing Makefile. It uses different object, library and executable extensions, sets CC and CFLAGS for 64 and 32bit Windows build. Target root has been added to build zdump and zic. Version and version.h rules were changed to batch. --- Makefile.nmake | 934 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++ getopt.c | 110 +++++++ localtime.c | 23 ++ private.h | 4 + zdump.c | 47 ++- zic.c | 14 + 6 files changed, 1128 insertions(+), 4 deletions(-) create mode 100644 Makefile.nmake create mode 100644 getopt.c diff --git a/Makefile.nmake b/Makefile.nmake new file mode 100644 index 0000000..730523e --- /dev/null +++ b/Makefile.nmake @@ -0,0 +1,934 @@ +# This file is in the public domain, so clarified as of +# 2009-05-17 by Arthur David Olson. + +# This file supports building zic.exe and zdump.exe with Visual Studio nmake + +# Package name for the code distribution. +PACKAGE= tzcode + +# Version number for the distribution, overridden in the 'tarballs' rule below. +VERSION= unknown + +# Email address for bug reports. +BUGEMAIL= tz(a)iana.org + +# Change the line below for your time zone (after finding the zone you want in +# the time zone files, or adding it to a time zone file). +# Alternately, if you discover you've got the wrong time zone, you can just +# zic -l rightzone +# to correct things. +# Use the command +# make zonenames +# to get a list of the values you can use for LOCALTIME. + +LOCALTIME= GMT + +# If you want something other than Eastern United States time as a template +# for handling POSIX-style time zone environment variables, +# change the line below (after finding the zone you want in the +# time zone files, or adding it to a time zone file). +# (When a POSIX-style environment variable is handled, the rules in the +# template file are used to determine "spring forward" and "fall back" days and +# times; the environment variable itself specifies UT offsets of standard and +# summer time.) +# Alternately, if you discover you've got the wrong time zone, you can just +# zic -p rightzone +# to correct things. +# Use the command +# make zonenames +# to get a list of the values you can use for POSIXRULES. +# If you want POSIX compatibility, use "America/New_York". + +POSIXRULES= America/New_York + +# Also see TZDEFRULESTRING below, which takes effect only +# if the time zone files cannot be accessed. + + +# Installation locations. +# +# The defaults are suitable for Debian, except that if REDO is +# posix_right or right_posix then files that Debian puts under +# /usr/share/zoneinfo/posix and /usr/share/zoneinfo/right are instead +# put under /usr/share/zoneinfo-posix and /usr/share/zoneinfo-leaps, +# respectively.
