Havranek et al. on DST's effect on energy consumption
by Paul Eggert Dec. 18, 2016

Dec. 18, 2016

A recent meta-analysis of energy savings due to daylight-saving time found a mean effect close to zero (the weighted mean of 0.343% was less than the estimated standard error). The largest energy savings from DST was found in high-latitude countries; areas closer to the equator tended to have negative energy savings. Studies published in journals with high impact factors tended to be more pessimistic about energy-savings benefits. The study concluded, "the effects of daylight saving time on energy consumption are too small to justify the biannual time-shifting." Havranek T, Herman D, Irsova Z. Does daylight saving save energy? a meta-analysis. MPRA Paper No. 74518 (2016-10-12). https://mpra.ub.uni-muenchen.de/74518/1/MPRA_paper_74518.pdf

Re: [tz] Request to add entry to "Programmatic interfaces that map geographical coordinates"
by Evan Siroky Dec. 17, 2016

Dec. 17, 2016

The package tz-lookup and geo-tz are independent of each other. As far as I know, the major difference between the two is the data source that is used. geo-tz is released under the MIT license. Feel free to link to the timezone tag. Although in my opinion a lot of the packages aren't the best because they don't get updated frequently enough with changes to the timezone db.

What's a good way to do that? Currently tz-link.htm says: <li>The <a href="https://www.npmjs.com/package/tz-lookup">tz-lookup module</a> for <a href="https://nodejs.org/en/">Node.js</a> is in the public domain.</li> How should the relationship between tz-lookup and geo-tz be described? Also, what's the license for geo-tz? It is not obvious from its web page. In looking at <https://www.npmjs.com/browse/keyword/timezone> I see several more Node.js time zone packages that seem relevant. Perhaps we should link to that page?

Ecuador DST in 1992/93
by Alois Treindl Dec. 15, 2016

Dec. 15, 2016

A client born in Ecuador wrote to me: "I need a little help with something plus I don't know who else can help me besides Astro! When I was born, the President of Ecuador changed the time zone (one hour ahead) from Nov/28/1992 to Feb/05/1993 because of problems with energy and there were a lot of power cuts across the country. " I checked the tzdata/southamerica file which holds for Ecuador: # Ecuador # # Milne says the Central and South American Telegraph Company used -5:24:15. # # From Paul Eggert (2007-03-04): # Apparently Ecuador had a failed experiment with DST in 1992. # <http://midena.gov.ec/content/view/1261/208/> (2007-02-27) and # <http://www.hoy.com.ec/NoticiaNue.asp?row_id=249856> (2006-11-06) both # talk about "hora Sixto". Leave this alone for now, as we have no data. # # Zone NAME GMTOFF RULES FORMAT [UNTIL] Zone America/Guayaquil -5:19:20 - LMT 1890 -5:14:00 - QMT 1931 # Quito Mean Time -5:00 - ECT # Ecuador Time The two links in the comment to not work. I search the web and came up with this link: http://www.elcomercio.com/actualidad/hora-sixto-1993.html which says: Al inicio de su mandato, el Gobierno Nacional, mediante Decreto Presidencial no. 285, obligó que todos los ecuatorianos adelantaran una hora en sus relojes para “ aprovechar la luz solar” y disminuir el consumo de energía. Fue la llamada ‘hora de Sixto’, que se aplicó desde el 28 de noviembre de 1992 hasta el 5 de febrero de 1993. Incluso, los estudiantes de todos los niveles educativos estuvieron obligados a iniciar clases a las 06:00 y terminar antes del mediodía. Google translation: At the beginning of his term, the National Government, through Presidential Decree no. 285, forced all Ecuadorians to advance an hour in their watches to "take advantage of sunlight" and reduce energy consumption. It was the so-called 'Sixtus hour', which was applied from November 28, 1992 until February 5, 1993. Even students of all educational levels were forced to start classes at 06:00 and finish before midday. There should probably be a rule: Rule ECU 1992 only - Nov 28 0:00 1:00 S Rule ECU 1993 only - Feb 5 0:00 0 - and the last lines of the existing entry should refer to this rule. Whether the law applied also to Galapagos, I do not know.

west Qinghai listed in two different time zones
by Jeffrey Oldham Dec. 9, 2016

Dec. 9, 2016

In tzdata2016f.tar.gz / asia, "west Qinghai" is listed under Asia/Chongqing (line 410) and also under Asia/Urumqi (line 418). I believe the former should be east Qinghai. Thanks, Jeffrey D. Oldham oldham(a)google.com

hundreds demonstrate against clock changes in Northern Cyprus
by Paul Eggert Dec. 6, 2016

Dec. 6, 2016

Hundreds of union members and students demonstrated yesterday in northern Cyprus, protesting the decision to remain on +03 all year. This follows a school bus collision Tuesday morning, which killed the driver and two schoolgirls, and which was blamed in part on early-morning darkness.
