NIST leap-second file not yet updated
by Martin Burnicki Feb. 23, 2016

Feb. 23, 2016

Hi all, please note the NIST leap-second file at ftp://time.nist.gov/pub/ has not yet been updated according to IERS bulletin C 51. It's still the version which has been published in July 2015, and will expire in June 2016. I saw that also tzdata2016a.tar.gz which has been published 2016-01-26 still contains the old leap second file even though bulletin C 51 has already been published 2016-01-11. I've dropped Judah Levine a similar note, but eventually you can include the IERS version of the file into the TZ DB distribution. The IERS file has already been updated and expires 2016-12-28.

7 regions in Russia submitted draft bills to change their time zones
by Alexander Krivenyshev Feb. 18, 2016

Feb. 18, 2016

After researching several official government documents (duma.gov.ru), there are at least 7 regions in Russia (not 3) that have submitted draft bills proposing changes to their time zones. Those regions are: - Zabaykalsky Krai / Chita (draft bill date of entry July 16, 2015)- has recently received approval to change time zone from UTC+8 to UTC+9 - Astrakhan Oblast / Astrakhan (draft bill date of entry Aug. 15, 2015), UTC+3 to UTC+4 - Sakhalin Oblast / Yuzhno-Sakhalinsk (draft bill date of entry Sep. 28, 2015), UTC+10 to UTC+11 - Ulyanovsk Oblast / Ulyanovsk (draft bill date of entry Nov. 03, 2015), UTC+3 to UTC+4 - Altai republic / Gorno-Altaysk (draft bill date of entry Nov. 23, 2015), UTC+6 to UTC+7 - Altai Krai / Barnaul (draft bill date of entry Dec. 03, 2015), UTC+6 to UTC+7 - Magadan Oblast / Magadan (draft bill date of entry Dec. 08, 2015), UTC+10 to UTC+11 See as a reference Russia map with 7 regions to change their time zones (darker colors of blue, green, red): http://www.worldtimezone.com/russia-time-zones-map-2016-04.gif (vs current http://www.worldtimezone.com/time-russia12.php) Seems that draft bill in Russia must pass through the following phases before being signed into law: Phase 1- The State Duma Council draft bill review Phase 2- Pass three (3) readings/revisions by the State Duma Phase 3- Approval by the Federation Council Phase 4- Signed by the President. Currently there are 6 additional regions in Russia that have requested to change their time zones (make amendments to the current Federal Law "On the calculation of time"), those draft bills were introduced at different times and are in different phases of the approval (or rejection) process. To make it easier to understand, below are the approximate phases of the remaining regions requesting time zones changes: - Sakhalin Oblast / Yuzhno-Sakhalinsk - Phase 1 (introduced to the State Duma Council) - Astrakhan Oblast / Astrakhan - Phase 2 ( first reading by the State Duma) - Ulyanovsk Oblast / Ulyanovsk - Phase 1 (introduced to the State Duma Council) - Altai republic / Gorno-Altaysk - Phase 1 (introduced to the State Duma Council) - Altai Krai / Barnaul - Phase 1 (introduced to the State Duma Council) - Magadan Oblast / Magadan - Phase 1 ( introduced to the Chairman of the State Duma- part of the State Duma Council) It is hard to say, how many above regions will be able to get through all these phases and change their time zones by March 27, 2016. We will try to keep our eyes on it. Alexander Krivenyshev http://www.worldtimezone.com

Hi Folks, Finally, there is a resolution by Uruguayan government on June the 29th, 2015, that the timezone for Uruguay will be GMT-3 (UTC-3) from now on (not just for this summer as initially announced). Just to make it permanently in the TZ data archive (in case was done only for this summer). ... hope not to change ever again! Regards, Nicolas

We crossed that bridge many years ago, so we shouldn't be giving any such people much more grief than we're already giving them. There have been non-upper-case-alpha abbreviations in the tz database since nearly day one. For example, in our repository the very first version of the 'europe' file (dated 1986) had spaces in some abbreviations, and spaces are much harder to parse than digits or plus signs are. In the current release, Pacific/Guam uses abbreviations that are not upper case alpha. Also, POSIX has blessed digits and plus signs in the abbreviations for quite some time; see <https://mm.icann.org/pipermail/tz/2001-January/011305.html>.

[PATCH 1/3] zone*.tab: make consistent 'most locations'
by J William Piggott Feb. 13, 2016

Feb. 13, 2016

modified: zone.tab modified: zone1970.tab The comments (field 4) inconsistently use leading area names. This causes tzselect's output to be mixed: Please select one of the following time zone regions. 1) Buenos Aires (BA, CF) 2) most locations (CB, CC, CN, ER, FM, MN, SE, SF) Please select one of the following time zone regions. 1) Lord Howe Island 2) Macquarie Island 3) Tasmania - most locations The leading name is absent from entries when it would match the chosen country, but sometimes the chosen country is no longer visible. Including the country name doesn't hurt anything and it improves readability.

Hello, As a new contributor to the Time Zone Database, I'd like to know if there is a way to ascertain the status of a submission? Specifically are the following queued for review, under review, rejected ... or? http://mm.icann.org/pipermail/tz/2016-January/023085.html http://mm.icann.org/pipermail/tz/2016-January/023090.html http://mm.icann.org/pipermail/tz/2016-January/023096.html I ask because I have more work to submit, but I do not want to continue stacking patch sets on top of rejected sets. Thank you, Willie

[tz-announce] 2016a release of tz code and data available
by Paul Eggert Jan. 28, 2016

Jan. 28, 2016

The 2016a 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: Changes affecting future time stamps America/Cayman will not observe daylight saving this year after all. Revert our guess that it would. (Thanks to Matt Johnson.) Asia/Chita switches from +0800 to +0900 on 2016-03-27 at 02:00. (Thanks to Alexander Krivenyshev.) Asia/Tehran now has DST predictions for the year 2038 and later, to be March 21 00:00 to September 21 00:00. This is likely better than predicting no DST, albeit off by a day every now and then. Changes affecting past and future time stamps America/Metlakatla switched from PST all year to AKST/AKDT on 2015-11-01 at 02:00. (Thanks to Steffen Thorsen.) America/Santa_Isabel has been removed, and replaced with a backward compatibility link to America/Tijuana. Its contents were apparently based on a misreading of Mexican legislation. Changes affecting past time stamps Asia/Karachi's two transition times in 2002 were off by a minute. (Thanks to Matt Johnson.) Changes affecting build procedure An installer can now combine leap seconds with use of the backzone file, e.g., with 'make PACKRATDATA=backzone REDO=posix_right zones'. The old 'make posix_packrat' rule is now marked as obsolescent. (Thanks to Ian Abbott for an initial implementation.) Changes affecting documentation and commentary A new file LICENSE makes it easier to see that the code and data are mostly public-domain. (Thanks to James Knight.) The three non-public-domain files now use the current (3-clause) BSD license instead of older versions of that license. tz-link.htm mentions the BDE library (thanks to Andrew Paprocki), CCTZ (thanks to Tim Parenti), TimeJones.com, and has a new section on editing tz source files (with a mention of Sublime zoneinfo, thanks to Gilmore Davidson). The Theory and asia files now mention the 2015 book "The Global Transformation of Time, 1870-1950", and cite a couple of reviews. The America/Chicago entry now documents the informal use of US central time in Fort Pierre, South Dakota. (Thanks to Rick McDermid, Matt Johnson, and Steve Jones.) Here are links to the release files: ftp://ftp.iana.org/tz/releases/tzcode2016a.tar.gz ftp://ftp.iana.org/tz/releases/tzdata2016a.tar.gz The files are also available via HTTP as follows: http://www.iana.org/time-zones/repository/releases/tzcode2016a.tar.gz http://www.iana.org/time-zones/repository/releases/tzdata2016a.tar.gz As usual, links to the latest release files are here: http://www.iana.org/time-zones/repository/tzcode-latest.tar.gz http://www.iana.org/time-zones/repository/tzdata-latest.tar.gz ftp://ftp.iana.org/tz/tzcode-latest.tar.gz ftp://ftp.iana.org/tz/tzdata-latest.tar.gz Each release file has a GPG signature, which can be retrieved by appending ".asc" to the above URLs.

Opposition to Cayman DST
by Paul Eggert Jan. 27, 2016

Jan. 27, 2016

Currently tzdata is guessing that Cayman will introduce daylight saving time this year. This is not official, though. There is opposition in the Legislative Assembly, and if the LA rejects it we will need to update tzdata. Ragoonath R. Gov’t Daylight Savings Time plans to get resistance in LA.

Re: [tz] Opposition to Cayman DST

Jan. 27, 2016

A complex area, timewise: http://OnTimeZone.com/images/caribbean.jpg (includes recent changes in Quinta Roo and the Turks and Caicos.) (magenta lines = time zone borders) (blue lines = dst observance borders) I wonder if the recent thaw in US/Cuban relations will have any tangential change in the economic relationship between the Caymans and Cuba. If so it might increase pressure to adopt DST. Steve Jones

If you lie about the time zone, your iPhone will have its revenge
by Paul Eggert Jan. 22, 2016

Jan. 22, 2016

iPhone 6s and iPhone 6s Plus users are reporting that their phones are sometimes showing plenty of charge left even though their batteries are actually depleted, leaving some users stranded out of power. Apparently users who change their time (e.g., to gain unfair advantage in games like Candy Crush Saga) can confuse iOS 9.2 into not updating the battery percentage indicator. A similar problem can occur to users who set the time zone manually. One workaround is to reboot and revert to getting date and time from the network. Reference: Smith J. iPhone 6s battery bug leaves users longing for iOS 9.3. GottaBeMobile.com 2016-01-17. http://www.gottabemobile.com/2016/01/17/iphone-6s-battery-bug-leaves-users-…

OK, thanks, attached are a few followup patches. The first adjusts white space, the second fixes a glitch I introduced earlier. The test cases still fail, though. I wonder why they fail for me and not for you? Some more things I noticed. testsuite.c assumes time_t is equivalent to long, by using the %ld printf format to print it. That's not portable. time_t might have a different width from long, and time_t might be unsigned. zdump.c's tformat function gets it right. Adding 1900 to tm_year can overflow, if tm_year is close to INT_MAX. quick_timegm is full of gotchas like that. As it's not needed and is likely to have bugs in testing, how about if we remove it? This is in the 3rd attached patch. The remaining uses of isleap have a similar problem. It would be better to use isleap_sum; see tzfile.h.

tzcode test suite
by scs＠eskimo.com Jan. 16, 2016

Jan. 16, 2016

I've been doing some surgery on localtime.c (perhaps more on that later), and to check my work I felt the need for a decent gmtime/localtime/mktime test suite. I'm sure such a thing has been written numbers of times before, and there may be some reason not to have one in the tzcode distribution, but if not, I'd like to donate this one for inclusion. It runs in two modes, one driven by a script containing (in effect) a list of known-good (time_t, struct tm) pairs, and another which exhaustively runs a potentially very large set of synthesized tests over a specified range. The script contains lines such as gmtime 1234567890 2009-02-13 23:31:30 and tz America/New_York localtime 483811200 1985-05-01 12:00:00 z=EDT o=-14400 dst=1 which are used to drive reciprocal pairs of tests on gmtime/timegm or localtime/mktime, in a reasonably obvious way. A line like the first one tests both that gmtime(1234567890) gives 2009-02-13, and also that timegm on 2009-02-13 23:31:30 gives 1234567890. There are keywords for setting the expected output values for zone, offset, and DST flag (as shown). There are also additional keywords to set the expected values of tm_wday and tm_yday. (See the attached test script for more examples.) I'm also enclosing a patch to the tzcode Makefile to add a "make tests" target, building and appropriately invoking this tool. At the moment this tool tests only localtime, gmtime, mktime, and timegm. It would make sense to have coverage of ctime and strftime, too, which would be straightforward enough to add. Note that the zone names in the attached 'testcases' script match those built by the stock tzdata distribution, but not necessarily those installed on the machine where you may be trying to run this. See the long comment at the top of testsuite.c for additional information. Enjoy! Steve Summit scs(a)eskimo.com

Bulletin C 51: No leap second in June 2016, but new leap second file
by Martin Burnicki Jan. 13, 2016

Jan. 13, 2016

The International Earth rotation Service (IERS) has just published bulletin C 51, announcing that *no* leap second will be introduced at the end of June 2016: ftp://hpiers.obspm.fr/iers/bul/bulc/bulletinc.dat The IERS now also makes a leap second file available for use with NTP: https://hpiers.obspm.fr/iers/bul/bulc/ntp/leap-seconds.list This new file has the expiration date set to 28 December 2016, so users who have configured ntpd to use the leap second file should upgrade their local copy of the file. The leap second file does not only announce leap seconds, it also provides ntpd and thus the OS kernel with the current TAI/UTC offset, which is helpful for applications working with TAI.

Hi, Dear IANA I met some problem in time zone data. >From the timeanddate.com, we know the time zone have some changes. [cid:image001.png@01D1488F.C9B0DEB0] But it seemed that iana.org did not update the time zone data about two months. [cid:image002.png@01D1488F.C9B0DEB0] So, I'd like to know if iana.org stop maintaining the time zone data. Could you give some suggestion about this.
