This looks like a bug to me, and my Perl tools that parse the files still come up with just 2 transitions per year.

Cairo/Egypt
by Frank Bean June 16, 2016

June 16, 2016

I just saw this update and need to add some detail I think. Africa/Cairo observes DST in 2016 from July 7 to the end of October. Guess October 27 and 24:00 transitions. (Thanks to Steffen Thorsen.) For future years, guess April's last Thursday to October's last Thursday except for Ramadan. Now, this may change next year but the current story from Egypt's government is that they will not be implementing DST until the end of Ramadan going forward.

the final second before standard time daylight savings time transitions
by Inman, Mark H CIV USARMY HQDA (US) June 15, 2016

June 15, 2016

Hello, Is there any official documentation on the time zone for March 13 2016 in New York City, when the clock says 1:59:59.99991000 ? My guess would be that it is EST or -04:00 offset, but I cannot find anything that discussed the fractions of the last second. We store fractions of seconds, and we need to be able to convert to a particular offset. Thanks for your work and your consideration. P.S. I have enjoyed the notes in the time zone rules. Most Respectfully, Mark Inman Army Analytics Group Email: mark.h.inman2.civ(a)mail.mil Personal Work Phone: 707-863-7150 Personal Cell Phone: 925-324-9864 Personal Cell Text: 9253249864(a)vtext.com

[tz-announce] 2016e release of tz code and data available
by Paul Eggert June 14, 2016

June 14, 2016

The 2016e 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 Africa/Cairo observes DST in 2016 from July 7 to the end of October. Guess October 27 and 24:00 transitions. (Thanks to Steffen Thorsen.) For future years, guess April's last Thursday to October's last Thursday except for Ramadan. Changes affecting past time stamps Locations while uninhabited now use '-00', not 'zzz', as a placeholder time zone abbreviation. This is inspired by Internet RFC 3339 and is more consistent with numeric time zone abbreviations already used elsewhere. The change affects several arctic and antarctic locations, e.g., America/Cambridge_Bay before 1920 and Antarctica/Troll before 2005. Asia/Baku's 1992-09-27 transition from +04 (DST) to +04 (non-DST) was at 03:00, not 23:00 the previous day. (Thanks to Michael Deckers.) Changes to code zic now outputs a dummy transition at time 2**31 - 1 in zones whose POSIX-style TZ strings contain a '<'. This mostly works around Qt bug 53071 <https://bugreports.qt.io/browse/QTBUG-53071>. (Thanks to Zhanibek Adilbekov for reporting the Qt bug.) Changes affecting documentation and commentary tz-link.htm says why governments should give plenty of notice for time zone or DST changes, and refers to Matt Johnson's blog post. tz-link.htm mentions Tzdata for Elixir. (Thanks to Matt Johnson.) Here are links to the release files: ftp://ftp.iana.org/tz/releases/tzcode2016e.tar.gz ftp://ftp.iana.org/tz/releases/tzdata2016e.tar.gz The files are also available via HTTP as follows: http://www.iana.org/time-zones/repository/releases/tzcode2016e.tar.gz http://www.iana.org/time-zones/repository/releases/tzdata2016e.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.

daylight saving and hospital admissions due to trampolines
by Paul Eggert June 10, 2016

June 10, 2016

A research paper published today concludes that in New Zealand, the October spring-forward transition is associated with increased incidence of hospital admissions for trampoline-related injuries for children aged 0-15. The most common injuries are fracture of the radius and/or ulna, and humeral fracture. Children aged 5-9 were responsible for almost half the studied injuries, followed by children aged 0-4. Sources: Yule MS, Krishna S, Rahiri J-S, Hill AG. Trampoline-associated injuries are more common in children in spring. NZ Med J 129:1436 (2016-06-10), 6916. https://www.nzma.org.nz/journal/read-the-journal/all-issues/2010-2019/2016/… Thomas R.

Asia/Tomsk
by Victor Sudakov June 7, 2016

June 7, 2016

Dear Colleagues, As a citizen of Tomsk, I would like to raise some questions concerning the recent addition of the Asia/Tomsk timezone. As you know, this time zone's abbreviation is all numeric: Zone Asia/Tomsk 5:39:51 - LMT 1919 Dec 22 6:00 - +06 1930 Jun 21 7:00 Russia +07/+08 1991 Mar 31 2:00s 6:00 Russia +06/+07 1992 Jan 19 2:00s 7:00 Russia +07/+08 2002 May 1 3:00 6:00 Russia +06/+07 2011 Mar 27 2:00s 7:00 - +07 2014 Oct 26 2:00s 6:00 - +06 2016 May 29 2:00s 7:00 - +07 In my opinion, it is bad for two reasons: 1. zic warns that 'warning: time zone abbreviation differs from POSIX standard (+06)' 2. Such an abbreviation is not user friendly and even borders on offensive. A locality deserves a name! Could we do something about Asia/Tomsk and other zones with share the same fate: Europe/Astrakhan, Europe/Kirov, Europe/Ulyanovsk, Asia/Barnaul? Thank you for your attention. -- Victor Sudakov, VAS4-RIPE, VAS47-RIPN sip:sudakov@sibptus.tomsk.ru
