Chile time changed early?
by Matt Johnson May 13, 2016

May 13, 2016

http://www.wsj.com/articles/what-time-is-it-in-chile-theres-no-telling-1463… Since the change isn't scheduled until Sunday, the only way I can think that this happened is that the cell towers were updated prematurely. Can anyone confirm or comment? -Matt

America/ Santiago possible Correction
by Gretchen Gottsacker May 12, 2016

May 12, 2016

Greetings, I noticed there may be a discrepancy for the time zone America/ Santiago. As mentioned in the document NEWS "Also, call the period from 2014-09-07 through 2016-05-14 daylight saving time instead of standard time, as that seems more appropriate now." I believe is an incorrect statement as the link provided on the southamerica document provides these two links http://www.diariooficial.interior.gob.cl/versiones-anteriores/do/20160318/ and http://www.leychile.cl/Navegar?idNorma=1088502 which states that "as amended by Presidential Decree Nº106, 2015, both the Ministry of the Interior and Public Security, will be extended, as regards the year 2016, until 24 pm the second Saturday of May. Also, starting from the 24 hours of the second Saturday in August 2016 and until 24 pm the second Saturday in May 2017, the official time will advance in 60 minutes" Meaning daylight savings is not active until August 2016.

TZ Changing in Chile on May, 14th.
by Luis Martinez Villa May 3, 2016

May 3, 2016

Dear IANA TZ, Since the last time change Chile has been in GMT-3 (i.e. Chile is right now in GMT-3). Chile is going to GMT-4 in May,14th midnight and returning to GMT-3 in August, 13th midnight. That means clocks will go back 1 hour at 00:00 May 15th (jumping back to May 14th); and will go forward by 1 hour on 00:00, August 14th. In tzdata2016c I can see this new rules for Chile: # Rule NAME FROM TO TYPE IN ON AT SAVE LETTER/S Rule Chile 2016 max - May Sun>=9 3:00u 0 - Rule Chile 2016 max - Aug Sun>=9 4:00u 1:00 S And I can see this Chile zone definition: # Zone NAME GMTOFF RULES FORMAT [UNTIL] Zone America/Santiago -4:42:46 - LMT 1890 -4:42:46 - SMT 1910 Jan 10 # Santiago Mean Time -5:00 - CLT 1916 Jul 1 # Chile Time -4:42:46 - SMT 1918 Sep 10 -4:00 - CLT 1919 Jul 1 -4:42:46 - SMT 1927 Sep 1 -5:00 Chile CL%sT 1932 Sep 1 -4:00 - CLT 1942 Jun 1 -5:00 - CLT 1942 Aug 1 -4:00 - CLT 1946 Jul 15 -4:00 1:00 CLST 1946 Sep 1 # central Chile -4:00 - CLT 1947 Apr 1 -5:00 - CLT 1947 May 21 23:00 -4:00 Chile CL%sT But with these two information I'm not sure that in the midnight of May, 14th this tzdata2016c will change the TZ of Chile from GMT-3 to GMT-4. Can you please explain me how these structures in tzdata2016c work to accomplish the necessary TZ change in Chile. Thank you very much, best regards. Luis

Programmatic way of determining the latest release number?
by Jon Skeet April 30, 2016

April 30, 2016

Hi folks, I'm aware of the ability to use ftp://ftp.iana.org/tz/tzcode-latest.tar.gz and the similar data URL to get the latest actual files, but is there a URL which either serves an HTTP redirect to the latest version, or gives the latest version number in some other easily-retrievable machine-readable format? I could parse the content of http://www.iana.org/time-zones, but that doesn't feel like a very robust approach :) Presumably this might all drop out of the tzdist work, but I was wondering whether there was a low-tech way at the moment.

Re: [tz] Issue in Time Zone Database for Kazakhstan's zones

I found what appears to be a related bug in the way that Qt handles data from tz 2016b, so the problem is not limited to tz 2016d. I can reproduce the problem by using just the Qt base, without involving KDE or Plasma. The Qt base parses tz data directly (!), and appears to do so incorrectly. I have filed a Qt bug report here: https://bugreports.qt.io/browse/QTBUG-53071 zic.c already has workarounds for buggy programs that misparse tzdata files containing time stamps far in the past, by putting in a no-change transition before the Big Bang. Perhaps there could be a similar workaround for this Qt bug, as Qt appears to mishandle tzdata files where the predicted future uses a POSIX TZ string that assumes POSIX.1-2001 or later. That is, perhaps we can work around the Qt bug by appending to the binary data some sort of no-change transition far enough in the future that we can expect Qt to be fixed in the field before most users care about those future time stamps. The year 2116, say?
