Time in Kenya
by P Chan Oct. 24, 2020

Oct. 24, 2020

The standard time of GMT+2:30 was adopted in the East Africa Protectorate on 1 May 1908. https://books.google.com/books?id=e-cAC-sjPSEC&pg=PA274 At midnight on 30 June 1928 the clocks throughout Kenya was put forward half an hour by the Alteration of Time Ordinance, 1928. https://gazettes.africa/archive/ke/1928/ke-government-gazette-dated-1928-05… https://books.google.com/books?id=2S0S6os32ZUC&pg=PA813 The 1928 ordinance was repeal by the Alteration of Time (repeal) Ordinance, 1929 and the time was restored to GMT+2:30 at midnight on 4 January 1930. https://books.google.com/books?id=_g18jIZQlwwC&pg=PA2701 The Alteration of Time Ordinance, 1936 changed the time to GMT+2:45 and repealed the previous ordinance at midnight on 31 December 1936 . https://books.google.com/books?id=K7j41z0aC5wC&pg=PA705 The Defence (Amendment of Laws No. 120) Regulations changed the time to GMT+3 at midnight on 31 July 1942. https://books.google.com/books?hl=zh-TW&id=c_E-AQAAIAAJ&pg=PA331 The provision of the 1936 ordinance was not repealed and was later incorporated in the Interpretation and General Clauses Ordinance in 1948. Although it was overridden by the 1942 regulations. https://dds.crl.edu/item/217517 (p.101) In 1950, the Interpretation and General Clauses Ordinance was amended to adopt GMT+3 permanently as the 1942 regulations were due to expire on 10 December. https://books.google.com/books?id=jvR8mUDAwR0C&pg=PA787 https://books.google.com/books?id=-_dQAQAAMAAJ&pg=PA294

make rearguard_tarballs fails creates tzdataunknown-rearguard.tar.gz file with latest tzdata lzip
by Carlos Jimenez Oct. 22, 2020

Oct. 22, 2020

Hello, I've encountered two issues with the two latest files for the tz changes: https://data.iana.org/time-zones/releases/tzdb-2020c.tar.lz https://www.iana.org/time-zones/repository/tzdb-latest.tar.lz 1) The touch command for the new pacificnew empty file won't work on centos6 or centos7. The date format syntax is generating an error: I noticed this was already fixed here: https://github.com/eggert/tz/commit/ce89cbaa436f336dca4b239fa528405abd7d84b… How long before that makes it to the /tzdb-2020c.tar.lz file? 2) Upon manually fixing the touch issue by replacing the touch command with the fixed version, I am now getting the wrong filenames for the rearguard file and tzcode and tzdata: Steps: [root@centos7 tzdb-2020c]# lzip -d tzdb-latest.tar.lz [root@centos7 tzdb-2020c]# mkdir tzdata-latest && tar xf tzdb-latest.tar -C tzdata-latest [root@centos7 tzdb-2020c]# pwd /home/tzdata/tzdata-2020c/tzdb-2020c [root@centos7 tzdb-2020c]# make rearguard_tarballs I get the following file as a result $tzdataunknown-rearguard.tar.gz I have reproduced this on centos6, centos7 and Mac OS 10.15.6. I get the following errors as well when I execute it: [root@centos6 tzdb-2020c]# make rearguard_tarballs >> ../../makeoutput.txt fatal: Not a git repository (or any of the parent directories): .git fatal: Not a git repository (or any of the parent directories): .git fatal: Not a git repository (or any of the parent directories): .git Attached is the make output. This impacts us directly since we have customers in Fiji. I'm trying to reverse engineer and review what may be going wrong but any help would be great. -Carlos

Support for Etc/GMT -style zones ids with partial hours
by Neil Fuller Oct. 22, 2020

Oct. 22, 2020

Would there be any support in this community for adding new Etc/GMT[-+] zone identifiers but with partial hours? e.g. something like "Etc/GMT-5:30" These might introduce some technical challenges, but I can see a use which I will explain below. I haven't yet investigated the impact on Android (where I deal with much of the time zone work), but I thought I'd ask for thoughts before expending any effort prototyping. Thanks, Neil. ------------------ Motivating case: Taking Android as an example, the platform uses TZDB zone identifiers as the basis for most time zone support. Directly, via a tzif-based file (used for libc mktime/localtime / Android's custom implementation of java.util.TimeZone), and indirectly via ICU4C and ICU4J. In situations like we had this week with Palestine, i.e. less than one week's notice before a DST transition change, the usual advice for users affected is "Please manually select an alternative time zone that has the offset you need until you receive a software update". e.g. Microsoft Windows appears to do the same [1] Side note: There are related cases for devices that have fallen out of their OEM's support window and will never receive a TZDB update again. The utility of these devices can degrade over time as their version of TZDB slowly drifts from the user's reality. Users continuing to use these devices may no longer be able to use the identifier for their actual location and get the behavior they need. Instead, they have to select an alternative zone ID that has the offset they need. If they're not lucky, they may be forced to pick an alternative zone ID which has its own DST schedule which might not match their requirements for the full year. The Stock Android settings UI, starting with Android Pie (9.0), allows users to select from the fixed "Etc/GMT-5" style identifiers from TZDB in addition to the more regular "Europe/London"-style zone identifiers associated with geographical regions. The original use case for this was to allow pilots to select Etc/UTC, and we added support for selecting all the other fixed Etc/GMT[+-] zones at the same time. The current Etc/GMT[+-] zone identifiers in TZDB only cover whole hour offsets. There are various places that use 30 minute offsets, and a few that use 45/15 minute offsets [2]. For the cases where devices cannot receive rules updates (in time, or at all), it would be useful to have the full range of 30-minute fixed-offset possibilities for users to select from instead. I'm choosing to ignore the 15/45 minute ones right now as they appear much less common / useful. Because most of our infrastructure treats TZDB as "ground truth" it would be beneficial to get this support in TZDB rather than carrying local patches to each library.

[PATCH] Port to downstream HP-UX-style ‘make’
by Paul Eggert Oct. 22, 2020

Oct. 22, 2020

HP-UX ‘make’ considers a target to be out-of-date if its timestamp equals that of a dependency, and POSIX allows this ‘make’ behavior. So, when putting timestamps on files in tarballs, add 1 to a file’s timestamp if it depends on some other file with the same timestamp. That way, when someone unpackages a tarball on an HP-UX host, its ‘make’ will avoid rebuilding files like ‘version’ that are up-to-date in the tarball. * Makefile (SET_TIMESTAMP_N, SET_TIMESTAMP, SET_TIMESTAMP_DEP): New macros. (set-timestamps.out, set-tzs-timestamp.out) (tzdata$(VERSION)-rearguard.tar.gz, tzdb-$(VERSION).tar.lz): Use them instead of invoking ‘touch’ by hand. (set-timestamps.out): Set the timestamp of tzdata.zi after that of version, since the former depends on the latter. --- Makefile | 43 +++++++++++++++++++++++++++++++++---------- 1 file changed, 33 insertions(+), 10 deletions(-) diff --git a/Makefile b/Makefile index 40b81d1..3b9d59e 100644 --- a/Makefile +++ b/Makefile @@ -872,11 +872,34 @@ $(MANTXTS): workman.sh LC_ALL=C sh workman.sh `expr $@ : '$.*$\.txt$$'` >$@.out mv $@.out $@ +# Set file timestamps deterministically if possible, +# so that tarballs containing the timestamps are reproducible. +# +# '$(SET_TIMESTAMP_N) N DEST A B C ...' sets the timestamp of the +# file DEST to the maximum of the timestamps of the files A B C ..., +# plus N if GNU ls and touch are available. +SET_TIMESTAMP_N = sh -c '\ + n=$$0 dest=$$1; shift; \ + touch -cmr `ls -t "$$@" | sed 1q` "$$dest" && \ + if test $$n != 0 && \ + lsout=`ls -n --time-style="+%s" "$$dest" 2>/dev/null`; then \ + set x $$lsout && \ + touch -cmd @`expr $$7 + $$n` "$$dest"; \ + else :; fi' +# If DEST depends on A B C ... in this Makefile, callers should use +# $(SET_TIMESTAMP_DEP) DEST A B C ..., for the benefit of any +# downstream 'make' that considers equal timestamps to be out of date. +# POSIX allows this 'make' behavior, and HP-UX 'make' does it. +# If all that matters is that the timestamp be reproducible +# and plausible, use $(SET_TIMESTAMP). +SET_TIMESTAMP = $(SET_TIMESTAMP_N) 0 +SET_TIMESTAMP_DEP = $(SET_TIMESTAMP_N) 1 + # Set the timestamps to those of the git repository, if available, # and if the files have not changed since then. -# This uses GNU 'touch' syntax 'touch -d@N FILE', -# where N is the number of seconds since 1970. -# If git or GNU 'touch' is absent, don't bother to sync with git timestamps. +# This uses GNU 'ls --time-style=+%s', which outputs the seconds count, +# and GNU 'touch -d@N FILE', where N is the number of seconds since 1970. +# If git or GNU is absent, don't bother to sync with git timestamps. # Also, set the timestamp of each prebuilt file like 'leapseconds' # to be the maximum of the files it depends on. set-timestamps.out: $(EIGHT_YARDS) @@ -894,16 +917,16 @@ set-timestamps.out: $(EIGHT_YARDS) fi || exit; \ done; \ fi - touch -cmr `ls -t $(LEAP_DEPS) | sed 1q` leapseconds + $(SET_TIMESTAMP_DEP) leapseconds $(LEAP_DEPS) for file in `ls $(MANTXTS) | sed 's/\.txt$$//'`; do \ - touch -cmr `ls -t $$file workman.sh | sed 1q` $$file.txt || \ + $(SET_TIMESTAMP_DEP) $$file.txt $$file workman.sh || \ exit; \ done - touch -cmr `ls -t $(TZDATA_ZI_DEPS) | sed 1q` tzdata.zi - touch -cmr `ls -t $(VERSION_DEPS) | sed 1q` version + $(SET_TIMESTAMP_DEP) version $(VERSION_DEPS) + $(SET_TIMESTAMP_DEP) tzdata.zi $(TZDATA_ZI_DEPS) touch $@ set-tzs-timestamp.out: $(TZS) - touch -cmr `ls -t $(TZS_DEPS) | sed 1q` $(TZS) + $(SET_TIMESTAMP_DEP) $(TZS) $(TZS_DEPS) touch $@ # The zics below ensure that each data file can stand on its own. @@ -1018,7 +1041,7 @@ tzdata$(VERSION)-rearguard.tar.gz: rearguard.zi set-timestamps.out for f in $(TDATA) $(PACKRATDATA); do \ rearf=tzdata$(VERSION)-rearguard.dir/$$f; \ $(AWK) -v DATAFORM=rearguard -f ziguard.awk $$f >$$rearf && \ - touch -cmr `ls -t ziguard.awk $$f` $$rearf || exit; \ + $(SET_TIMESTAMP_DEP) $$rearf ziguard.awk $$f || exit; \ done sed '1s/$$/-rearguard/' \ <version >tzdata$(VERSION)-rearguard.dir/version @@ -1037,7 +1060,7 @@ tzdb-$(VERSION).tar.lz: set-timestamps.out set-tzs-timestamp.out rm -fr tzdb-$(VERSION) mkdir tzdb-$(VERSION) ln $(ENCHILADA) tzdb-$(VERSION) - touch -cmr `ls -t tzdb-$(VERSION)/* | sed 1q` tzdb-$(VERSION) + $(SET_TIMESTAMP) tzdb-$(VERSION) tzdb-$(VERSION)/* LC_ALL=C && export LC_ALL && \ tar $(TARFLAGS) -cf - tzdb-$(VERSION) | lzip -9 >$@.out mv $@.out $@ -- 2.25.1

[tz-announce] 2020d release of tz code and data available
by Paul Eggert Oct. 21, 2020

Oct. 21, 2020

The 2020d 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: Palestine ends DST earlier than predicted, on 2020-10-24. Changes to past and future timestamps Palestine ends DST on 2020-10-24 at 01:00, instead of 2020-10-31 as previously predicted (thanks to Sharef Mustafa.) Its 2019-10-26 fall-back was at 00:00, not 01:00 (thanks to Steffen Thorsen.) Its 2015-10-23 transition was at 01:00 not 00:00, and its spring 2020 transition was on March 28 at 00:00, not March 27 (thanks to Pierre Cashon.) This affects Asia/Gaza and Asia/Hebron. Assume future spring and fall transitions will be on the Saturday preceding the last Sunday of March and October, respectively. Here are links to the release files: https://www.iana.org/time-zones/repository/releases/tzcode2020d.tar.gz https://www.iana.org/time-zones/repository/releases/tzdata2020d.tar.gz https://www.iana.org/time-zones/repository/releases/tzdb-2020d.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.

If your tzdata parser does not yet support negative DST offsets or times past 24:00, or if it insists on a 'pacificnew' file that is no longer present, this release's data entries can be turned into a rearguard-format tarball that should work even with these older parsers. This is intended to be a temporary transition aid for these parsers. To generate a rearguard-format tarball, obtain the full distribution as described above, and run the command 'make rearguard_tarballs' on a development host. Or you can run 'make rearguard.zi' to generate a single file that can be fed directly to a parser that works like 'zic'.

[tz-announce] 2020c release of tz code and data available
by Paul Eggert Oct. 20, 2020

Oct. 20, 2020

The 2020c 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: Fiji starts DST later than usual, on 2020-12-20. Changes to future timestamps Fiji will start DST on 2020-12-20, instead of 2020-11-08 as previously predicted. DST will still end on 2021-01-17. (Thanks to Raymond Kumar and Alan Mintz.) Assume for now that the later-than-usual start date is a one-time departure from the recent pattern. Changes to build procedure Rearguard tarballs now contain an empty file pacificnew. Some older downstream software expects this file to exist. (Problem reported by Mike Cullinan.) Here are links to the release files: https://www.iana.org/time-zones/repository/releases/tzcode2020c.tar.gz https://www.iana.org/time-zones/repository/releases/tzdata2020c.tar.gz https://www.iana.org/time-zones/repository/releases/tzdb-2020c.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. Each release file has a GPG signature, which can be retrieved by appending ".asc" to the above URLs. Copies of these signatures are appended to this message.

If your tzdata parser does not yet support negative DST offsets or times past 24:00, or if it insists on a 'pacificnew' file that is no longer present, this release's data entries can be turned into a rearguard-format tarball that should work even with these older parsers. This is intended to be a temporary transition aid for these parsers. To generate a rearguard-format tarball, obtain the full distribution as described above, and run the command 'make rearguard_tarballs' on a development host. Or you can run 'make rearguard.zi' to generate a single file that can be fed directly to a parser that works like 'zic'.
