Europe/Jersey and Europe/Guernsey did not follow London during the war and other backzone aliases also vary across Europe in that period Europe/Belfast followed Ireland pre 1968 and like Europe/Isle_of_Man switched to a standard time at a different date to the rest of the UK. All only little point's, but important differences in the pre 1970 chronology! These differences are validated data ... but missing if a distribution simply switches backzone off and while yes some backzone material is unverified, this particular section is very much verified. So how does one recognise that those aliases are returning the correct pre-1970 data and not just mirroring Europe/London or one of the other generic European rule sets? -- Lester Caine - G8HFL ----------------------------- Contact - http://lsces.co.uk/wiki/?page=contact L.S.Caine Electronic Services - http://lsces.co.uk EnquirySolve - http://enquirysolve.com/ Model Engineers Digital Workshop - http://medw.co.uk Rainbow Digital Media - http://rainbowdigitalmedia.co.uk

Timezone in Brazil
by MARCIO IKEDA Oct. 11, 2015

Oct. 11, 2015

This is Marcio Ikeda from LG Electronics in Brazil. Nice to meet you! I would like to know if there are some background history for timezones in Brazil. It seems that Brasilia city which is the capital, is only treated as a metaZone and not a timeZone. I would like to know if are there some discussions on why America/Brasilia is not in the list. And if It is possible to include it. This is causing people from QA here to question this. Thank you!

Not sure if this casts light or mud on the issue, but last year (Feb '14) I contacted a business on Isla Cedros (which is in Baja) about the local time, and received this reply (relevant passage underscored): >Mr Jones >Thank you for coming to us for the answer. >Cedros island is governed by the Baja California State, therefore >most of the time it has the same time zone Pacific shared by >California.

Re: [tz] America/Santa_Isabel
by Arthur David Olson Oct. 8, 2015

The use of Santa Isabel does indeed seem to be an error. I see, though, that San Felipe, like Santa Isabel, is part of the Mexicali municipality; San Felipe may also use U. S. rules. The "northamerica" file's quotation of the relevant decree mentions "los municipios de Tijuana y Mexicali" but only "la Ciudad de Ensenada" (rather than "el municipio"); we may get to use the largest city in the Ensenada municipality that's south of the city of Ensenada. That seems to be Rodolfo Sánchez Taboada (Maneadero) (22,957); the normal 14-character limit would suggest using Maneadero; it seems to have a larger population that San Felipe (16,702). Lázaro Cárdenas (16,294) is substantially farther south and thus likelier to use Mexican rules; some 14-character-limit creativity would be required. Of course if we were lucky we'd discover that Santa Isabel actually uses Mexican rules.-S --ado https://en.wikipedia.org/wiki/San_Felipe,_Baja_California https://en.wikipedia.org/wiki/Ensenada_Municipality

America/Santa_Isabel
by Matt Johnson Oct. 8, 2015

Oct. 8, 2015

Does anyone know why America/Santa_Isabel was chosen to represent the portion of Baja California (Mexico) that follows Mexican DST rules? Santa Isabel is just as close to the US border as Tijuana and Mexicali, which are in the America/Tijuana zone. According to Wikipedia ( https://en.wikipedia.org/wiki/Baja_California ) "Over 75% of the population lives in the capital city, Mexicali, in Ensenada, or in Tijuana. Other important cities include San Felipe, Rosarito and Tecate." Of those, it would seem Ensenda and San Felipe would be the only cities not near the US border, and my understanding is that Ensenada follows the US rules. Wouldn't then America/San_Felipe be a better choice?

Asia/Nicosia
by Steven Nicolaou Oct. 3, 2015

Oct. 3, 2015

Hi, I would like to propose that Asia/Nicosia move to Europe/Nicosia. The Asia file makes this statement: # Classically, Cyprus belongs to Asia; e.g. see Herodotus, Histories, I.72. # However, for various reasons many users expect to find it under Europe. While I appreciate the nod to classical antiquity, its classification under Asia is wholly irrelevant today. This statement appears to trivialize the "various reasons" why "many users" tend to expect it under Europe. . Cyprus is a European country . The culture is decidedly Europe-facing . It is a member state of the European Union . Its currency is the Euro . It has participated in the Eurovision Song Contest since 1981 . Its time zone is Eastern European Time (EET) . The predominant culture and language is Greek . The earliest historical reference to Cyprus in the 15th century BC was in Mycenaean Greek . The Asia file itself even mentions this: "# IATA SSIM (1998-09) has Cyprus using EU rules for the first time." There is nothing Asian about Cyprus today. Nobody in the country attempting to set the local time zone is going to look for it under Asia. If we don't find it under Europe, we assume it was erroneously omitted. Steven

Last weekend's daylight-saving confusion in Morocco
by Paul Eggert Oct. 1, 2015

Oct. 1, 2015

Thomas Savage reports confusion in Morocco last weekend involving daylight saving time. See: Savage T. Quelle heure est-il vraiment au Maroc? Telquel.ma 2015-09-30. http://telquel.ma/2015/09/30/quelle-heure-il-vraiment-au-maroc_1464578 Savage quotes last month's confusion on the tz mailing list over whether Morocco's fallback transition this year would be Sept. 27 (as an incorrect news report would have it) or Oct. 25 (the official date), and speculates that this confusion led to many electronic devices in Morocco to misbehave on Sept. 27. In thinking about the failure symptoms, though, I guess a more plausible explanation is that the malfunctioning devices were using the equivalent of a tz release somewhere from tzdata 2012c (dated 2012-03-07) through 2013g (dated 2013-09-30), as these older releases predicted that Morocco would fall back the last Sunday in September -- a prediction that was correct in 2012 but incorrect in 2013 through 2015.

[tz-announce] 2015g release of tz code and data available
by Paul Eggert Oct. 1, 2015

Oct. 1, 2015

The 2015g 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 Turkey's 2015 fall-back transition is scheduled for Nov. 8, not Oct. 25. (Thanks to Fatih.) Norfolk moves from +1130 to +1100 on 2015-10-04 at 02:00 local time. (Thanks to Alexander Krivenyshev.) Fiji's 2016 fall-back transition is scheduled for January 17, not 24. (Thanks to Ken Rylander.) Fort Nelson, British Columbia will not fall back on 2015-11-01. It has effectively been on MST (-0700) since it advanced its clocks on 2015-03-08. New zone America/Fort_Nelson. (Thanks to Matt Johnson.) Changes affecting past time stamps Norfolk observed DST from 1974-10-27 02:00 to 1975-03-02 02:00. Changes affecting code localtime no longer mishandles America/Anchorage after 2037. (Thanks to Bradley White for reporting the bug.) On hosts with signed 32-bit time_t, localtime no longer mishandles Pacific/Fiji after 2038-01-16 14:00 UTC. The localtime module allows the variables 'timezone', 'daylight', and 'altzone' to be in common storage shared with other modules, and declares them in case the system <time.h> does not. (Problems reported by Kees Dekker.) On platforms with tm_zone, strftime.c now assumes it is not NULL. This simplifies the code and is consistent with zdump.c. (Problem reported by Christos Zoulas.) Changes affecting documentation The tzfile man page now documents that transition times denote the starts (not the ends) of the corresponding time periods. (Ambiguity reported by Bill Seymour.)
