[tz-announce] 2016i release of tz code and data available
by Paul Eggert Nov. 3, 2016

Nov. 3, 2016

The 2016i 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: Briefly: Cyprus split into two time zones on 2016-10-30, and Tonga reintroduces DST on 2016-11-06. Changes to future time stamps Pacific/Tongatapu begins DST on 2016-11-06 at 02:00, ending on 2017-01-15 at 03:00. Assume future observances in Tonga will be from the first Sunday in November through the third Sunday in January, like Fiji. (Thanks to Pulu ʻAnau.) Switch to numeric time zone abbreviations for this zone. Changes to past and future time stamps Northern Cyprus is now +03 year round, causing a split in Cyprus time zones starting 2016-10-30 at 04:00. This creates a zone Asia/Famagusta. (Thanks to Even Scharning and Matt Johnson.) Antarctica/Casey switched from +08 to +11 on 2016-10-22. (Thanks to Steffen Thorsen.) Changes to past time stamps Several corrections were made for pre-1975 time stamps in Italy. These affect Europe/Malta, Europe/Rome, Europe/San_Marino, and Europe/Vatican. First, the 1893-11-01 00:00 transition in Italy used the new UT offset (+01), not the old (+00:49:56). (Thanks to Michael Deckers.) Second, rules for daylight saving in Italy were changed to agree with Italy's National Institute of Metrological Research (INRiM) except for 1944, as follows (thanks to Pierpaolo Bernardi, Brian Inglis, and Michael Deckers): The 1916-06-03 transition was at 24:00, not 00:00. The 1916-10-01, 1919-10-05, and 1920-09-19 transitions were at 00:00, not 01:00. The 1917-09-30 and 1918-10-06 transitions were at 24:00, not 01:00. The 1944-09-17 transition was at 03:00, not 01:00. This particular change is taken from Italian law as INRiM's table, (which says 02:00) appears to have a typo here. Also, keep the 1944-04-03 transition for Europe/Rome, as Rome was controlled by Germany then. The 1967-1970 and 1972-1974 fallback transitions were at 01:00, not 00:00. Changes to code The code should now be buildable on AmigaOS merely by setting the appropriate Makefile variables. (From a patch by Carsten Larsen.)

Re: [tz] Cyprus is splitting into two time zones
by Evan Siroky Nov. 2, 2016

Regarding the buffer zone, according to this Wikipedia Article (https://en.wikipedia.org/wiki/United_Nations_Buffer_Zone_in_Cyprus) "Turkish forces built a barrier on the zone's northern side". So maybe everything north of the buffer zone would be considered Asia/Famagusta and the whole buffer zone plus south of the buffer zone would be Asia/Nicosia.

EU Parliament debates DST
by Matt Johnson Oct. 28, 2016

Oct. 28, 2016

Yesterday there was an extensive debate in the European Union Parliament concerning daylight saving time. The recordings and text are available here: http://www.europarl.europa.eu/plenary/en/debate-details.html?date=20161027&… Expand the section titled: "15:04 - 16:05 Switch between summer and winter time (debate)" My favorite is the passionate argument made by Indrek Tarand, MEP from Estonia, at 15:34:21. Though I'm not sure his history is quite so accurate. ;-) Thanks to http://www.timeanddate.com/news/time/eu-debate-dst.html for the heads up. -Matt

Historical discrepancies for Italy.
by Pierpaolo Bernardi Oct. 27, 2016

Oct. 27, 2016

Hello, about Italian time, I see: # From Paul Eggert (2006-03-22): # For Italian DST we have three sources: Shanks & Pottenger, Whitman, and # F. Pollastri # Day-light Saving Time in Italy (2006-02-03) # http://toi.iriti.cnr.it/uk/ienitlt.html # ('FP' below), taken from an Italian National Electrotechnical Institute # publication. When the three sources disagree, guess who's right, as follows: I don't know about the other sources, but: - the url given to cnr.it is dead. - The authoritative source for time in Italy is the national metrological institute, which has a summary page of historical DST data at http://www.inrim.it/res/tf/ora_legale_i.shtml - Some of the data in TZ does not agree with this page. I think that there must be VERY strong evidence that the INRIM is wrong before preferring other sources? Cheers
