My (unpatched) Windows 7 machine extends the 2010 rule [Fourth Sunday October to Last Sunday March] on to infinity. They have published at least two updates since then that I've been able to find that tweak the rules, and I haven't verified firsthand but have no particular reason to doubt they similarly extend the then-latest rules [Fourth Sunday January to First Sunday March, based on update description text] indefinitely, and expect to publish further hotfixes. -- Random832

[PATCH 0/1] Add Asia/Beijing
by James M Leddy Aug. 19, 2012

Aug. 19, 2012

I know this is a controversial topic, but I've been asked to submit this, and have decided to do so for a few reasons: * We'll stop getting questions of why Beijing Time is not included. * People that want to ship their own modified version of tzdata can take this patch. * The common proposed fix is that we should be using "human presentable" names and have a mapping from these names to the actual timezones. Since that proposal, indeed since the inception of desktop Linux/Unix, no one (as far as I know) has actually done this, leading to continued confusion from users. * I've seen it argued that we have to keep the the database pristine, yet the bar for entry does not actually seem that high. For example, we have a link from the Vatican to Rome, even though it should be pretty obvious that they're the same time zone. And we have a Link for people that can't seem to figure out if Nicosia is in Europe or Asia. * This really does seem to confuse users. "Eastern Time" includes both Washington, D.C. and New York City. The justification is that we never added Washington to the list, so we shouldn't add Beijing. But this is really not a fair comparison. It's called "Beijing Time". I'm sure if ET was called "Washington Time", it would at least give me pause to select New York time, even though I'm a New Yorker. No one gets confused that they have to pick New York, or Madrid instead of Barcelona, so that argument doesn't hold water.

We could draw an arbitrary line to keep the number small. For example, there are (I think) about 540 existing IDs in the database, including all the links. If you draw that line at population 500,000, there are a little over 1000 cities that qualify, probably meaning (rough guess) the addition of 700-800 links - less than 80KB. I can't imagine that's an issue for any current embedded system, is it? Here's a sampling of the (mostly-not-well-known) cities on the 500K "bubble": Denpasar, Indonesia Lipetsk, Russia Dengta, China Tuxtla Gutiérrez, Mexico Songkhla, Thailand Mariupol, Ukraine Danjiangkou, China Chiclayo, Peru COPENHAGEN, Denmark Penglai, China Oaxaca de Juárez, Mexico Aba, Nigeria Astrakhan, Russia MACAO, China : Macao SAR Eskisehir, Turkey Shishi, China Kannur, India Ananindeua, Brazil Bokaro Steel City, India SAN SALVADOR, El Salvador Kolhapur, India Xinzhou, China Joinville, Brazil Dangyang, China Londrina, Brazil There might be cause to add some others below that line, like capital/commercial capital status, top "n" within a country (depending on area maybe), etc. It could also be completely or partially optional (e.g. 500k+, 100-500k, 50-100k pop files), allowing the specific implementation to choose to include as much or as little as they have room for. Include specific support for a "local" file that can override the stock database, and the implementation and user can do whatever they want. -- Alan Mintz <Alan_Mintz+TZ_IANA(a)Earthlink.net>

IIRC, given the history of time and calendars, it makes sense to have a separate time zone for the Vatican, even though it is currently the same :) Cultural enclaves often observe their own rules regarding time zones, as evidenced by several Native American entities in the US (Navajo, Hopi within Navajo, and Metlakatla come to mind). There has always been an issue with having identifiers named by cities only. Some of the US identifiers are not familiar to many people, even when they are within their own state. IMO, a separate table, containing links from at least the commercial capital of each country to its time zone, would seem to be the best solution. Specific support for a local version of the table (that would be preserved across updates) would be good, too. Save changes to the main rule files for real changes in parameters, not synonyms. -- Alan Mintz <Alan_Mintz+TZ_IANA(a)Earthlink.net>

Android (bionic) tzcode changes
by enh Aug. 9, 2012

Aug. 9, 2012

i've been maintaining Android's copy of the tzdata for several years now and have more recently inherited maintenance of Android's C library, bionic. i was looking at automating updates of tzcode (which hasn't been tracking upstream at all) but noticed that we have several extensions that i can't see upstream (in tzcode2012e): 1. Android concatenates all the data files into one big file that's indexed by a separate .idx file. the idea being that you binary search the index (by Olson id) to find the offset into the data of that zone's data. 2. Android implements the glibc strftime extensions (search for "an optional flag" in http://www.gnu.org/software/libc/manual/html_node/Formatting-Calendar-Time.… ). 3. Android implements strptime ( http://pubs.opengroup.org/onlinepubs/007904975/functions/strptime.html) including the glibc extensions. i might have to clean some of these up, but i was curious whether upstream would at least in theory be interested in any of this? i can see 1 being least interesting, so i might just have to factor our changes there out into other files as best i can. but 2 and 3 sound like they'd be of general interest? (also feel free to add Android to the web page's list of systems that rely on the tz database.) --elliott

Detecting a new release
by Neil Masson Aug. 3, 2012

Aug. 3, 2012

This might have been talked about recently, but I don't remember any resolution. I have a script which polls the IANA Website daily to detect if there has been any update. It parses the html to find the latest version and then checks to see if the version has changed since the last time. This solution is fragile and could easily be broken if the layout of the Website changes. I don't see any way of detecting the version from the ftp or rsync sites as the "real" filename which contains the version has been replaced with a link tzdata-latest.tar.gz. It would be better if a version file was added to the ftp and rsync sites which contained the version identifier of the release.

timegm() function and state
by Doug Bailey Aug. 3, 2012

Aug. 3, 2012

One of my users reported that the first time timegm() is called, it returns -1. Investigating, it seems that there's a problem with the gmtptr state. Take the following code: int main(int argc, char *argv[]) { struct tm localt; localt.tm_sec = 0; localt.tm_min = 0; localt.tm_hour = 0; localt.tm_mday = 1; localt.tm_year = 113; localt.tm_mon = 0; localt.tm_wday = 0; localt.tm_yday = 0; localt.tm_isdst = 0; localt.tm_gmtoff = 0; localt.tm_zone = 0; mktime(&localt); printf("asctime: %s", asctime(&localt)); printf("timegm(&localt) = %d (errno %s)\n", timegm(&localt), strerror(errno)); printf("timegm(&localt) = %d (errno %s)\n", timegm(&localt), strerror(errno)); printf("timegm(&localt) = %d (errno %s)\n", timegm(&localt), strerror(errno)); return 0; } Run it and you get: asctime: Tue Jan 1 00:00:00 2013 timegm(&localt) = -1 (errno No such process) timegm(&localt) = 1356998400 (errno No such process) timegm(&localt) = 1356998400 (errno No such process) The first time timegm() is invoked, it fails. Subsequent invocations work correctly. I didn't manage to track down the root problem, but I found if I forced gmtptr to load (as gmtsub should), then everything works correctly. time_t timegm(tmp) struct tm * const tmp; { if (!gmt_is_set) { gmt_is_set = TRUE; #ifdef ALL_STATE gmtptr = (struct state *) calloc(1, sizeof *gmtptr); if (gmtptr != NULL) #endif /* defined ALL_STATE */ gmtload(gmtptr); } if (tmp != NULL) tmp->tm_isdst = 0; return time1(tmp, gmtsub, 0L); } I just copied the gmt_is_set test from gmtsub. I realize that gmtsub gets called anyways (timegm->time1->time2->gmtsub), but maybe the context doesn't get loaded quickly enough. I haven't tested, but I suspect that timeoff will have the same problem since it also invokes time1(..,gmtsub,..) without first ensuring the gmt context is loaded. Doug

[PATCH 3/4] * .gitignore: New file.

It's not clear to me that the .gitignore file should be part of the tzcode or tzdata distributions, as it's needed only if you've gotten the files from the git repository, so for now the Makefile is not modified to add this to one or the other distribution. --- .gitignore | 10 ++++++++++ 1 file changed, 10 insertions(+) create mode 100644 .gitignore diff --git a/.gitignore b/.gitignore new file mode 100644 index 0000000..d36f26e --- /dev/null +++ b/.gitignore @@ -0,0 +1,10 @@ +*.o +*.tar.gz +*.txt +*~ +ChangeLog +tzselect +version.h +yearistype +zdump +zic -- 1.7.9.5

[PATCH 1/4] Remove trailing white space.
by Paul Eggert July 25, 2012

July 25, 2012

I hope to release a new version soon, since current time stamps are wrong in Tokelau. So, in preparation for that, here's the first of a set of four proposed patches to the tz code and data. This patch is purely clerical: it removes trailing white space (which my text editor does automatically) so that other patches don't have spurious differences. This proposed patch is also available as: https://github.com/eggert/tz/commit/369851954c101b5f51cdef65f73bb94ada790951 --- Theory | 28 +++++++++---------- asia | 86 +++++++++++++++++++++++++++++----------------------------- australasia | 28 +++++++++---------- europe | 14 +++++----- leapseconds | 6 ++-- northamerica | 24 ++++++++-------- southamerica | 18 ++++++------ 7 files changed, 102 insertions(+), 102 deletions(-) diff --git a/Theory b/Theory index 7094b27..e442bcd 100644 --- a/Theory +++ b/Theory @@ -194,26 +194,26 @@ better. ----- Scope of the tz database ----- -The tz database attempts to record the history and predicted future of -all computer-based clocks that track civil time.

Tokelau in wrong time zone?
by Steffen Thorsen July 25, 2012

July 25, 2012

The IANA tz database, Wikipedia, CIA World Fact Book, most time zone web sites and a lot of other sources claim that Tokelau is on UTC+14 (or UTC-10 if they have not corrected for the date line switch in December). However, we got a complaint a few weeks ago, from a user in Tokelau that our Tokelau time on timeanddate.com was one hour ahead of the actual time there. He claimed Tokelau had the same current time as Samoa (UTC+13) at the moment and he worked for the Tokelau Government. This lead us to investigate, we double checked by calling hotels and offices based in Tokelau asking about the time there, and they all told a time that agrees with UTC+13. So it was soon evident that Tokelau is on UTC+13. The next problem was to find when they changed from UTC+14, or if it might have happened as they moved from UTC-10 last December (skipping 23 hours instead of a full day). But sources agreed that there had not been any time change recently, Tokelau does not participate in DST and that the change last December was to skip a full day - and this means that Tokelau was on UTC-11 last year. We found some NZ government sources, saying UTC-11, one being as far back as 2005: http://www.mfat.govt.nz/downloads/foreign-relations/tokelau/tokelau-brochur… says "Local time: GMT –11." One from 2012, but that one has not adjusted for the date line change: http://www.nzte.govt.nz/explore-export-markets/australia-pacific/Documents/… says "Time zone: GMT -11 hours" So, Tokelau has probably been on UTC-11 (or +13) at least since year 2005. This makes me wonder, has Tokelau ever been on UTC-10? Looking in the record for Fakaofo, it says they changed from Local Mean Time in 1901, and then moved the clocks by nearly 85 minutes! I looked through the australasia file and could not find any other location that moved their clocks by more than 1 hour as they went from LMT to a standard time zone or a time zone somehow connected to GMT. (The vast majority adjusted by less than 30 minutes.) Currently we have: (tabs mangled) Zone Pacific/Fakaofo -11:24:56 - LMT 1901 -10:00 - TKT 2011 Dec 30 # Tokelau Time 14:00 - TKT Shanks says UTC-10 from 1901 and is probably the source here. I think there is a good chance the change actually was to UTC-11 back then, and that they have never changed their clocks after that - if not we would need to find some date between 1901 and 2005 that they changed their time zone. Don Higgins, Advisor to the Administrator of Tokelau raised the fact about the wrong time and has contributed significantly to our research. Best regards, Steffen Thorsen - timeanddate.com

tzcode2012c and tzdata2012d available
by Paul Eggert July 21, 2012

July 21, 2012

New versions of the tz code and data are now available from ftp://ftp.iana.org/tz/releases/tzcode2012c.tar.gz ftp://ftp.iana.org/tz/releases/tzdata2012d.tar.gz These reflect the changes for Morocco's time stamps, which take effect in a couple of hours, along with infrastructure changes to accommodate how the tz code and data are released on IANA. Sorry about the late release. I will send more details to the tz mailing list shortly.

unofficial tz repository on github
by Paul Eggert July 20, 2012

July 20, 2012

I've set up an unofficial repository containing the tz code and data at <https://github.com/eggert/tz>. This is supposed to contain the history of changes to the tz code and data, back to the first commit in 1984. I plan to use it to publish further proposed changes. The official tz distributions will remain in their current location, at <ftp://ftp.iana.org/tz/>. The tz code was formerly maintained as an SCCS repository, but nowadays Git seems more appropriate. Unfortunately no publicly-available SCCS-to-Git converter was up to the task of migrating the tz repository; the two I tried mishandled old time stamps and lost revisions! So I wrote my own. This task languished until Arthur David Olson's recent higher-priority message about Morocco <http://mm.icann.org/pipermail/tz/2012-July/018123.html>, which prompted me to move this task to the top of my list. The unofficial repository currently contains the latest public tz code and data distributions (tzcode2012b and tzdata2012c), with the following further modifications, each of which represents a proposed change: * Switch from SCCS to git. https://github.com/eggert/tz/commit/dccd5a16af62c52f2b49a2fe56270a710617cbbd This alters how version numbers are handled. * Morocco does not observe DST from Jul 20 03:00 to Aug 20 02:00. https://github.com/eggert/tz/commit/0e0bb39b15fbbaa759d66951ec727d640d17acc5 These are Arthur's changes for Morocco, with minor editing. * Adjust to iana.org distribution method. https://github.com/eggert/tz/commit/943c565e512880520c685c3233fa127f2341d3a3 This documents the switch to iana.org as a distribution site. * Fix HTML validation issues. https://github.com/eggert/tz/commit/8a52da39ed9a4988da930ded4946b0b24cc45f2c This is so that "make check" works again. I'll send details about these proposed changes in followup emails. Each email will contain one of the patches, along with a brief log entry describing its purpose. This is the style used by "git format-patch". Unfortunately I have not had time to look at the other changes that are pending. This will require looking through emails since about March, and merging the changes into the database. My impression is that these changes are less pressing, though, and I thought I'd get the Morocco change out first, and to make sure that this new distribution scheme works. Comments are welcome, especially those that fix bugs in the Morocco change or the development machinery.
