by Paul Eggert 25 May '15

25 May '15

It's March Madness time for daylight-saving rule changes. Here's a proposed change to the tz database to keep up with the latest political development, which affects time stamps starting March 29: * Latvia and Lithuania will not observe DST, starting this year.

Australia - Broken Hill - Yancowinna
by Oscar van Vlijmen 15 Dec '06

15 Dec '06

Broken Hill, or more precise, the whole county of Yancowinna, differs from the rest of New South Wales, as clearly stated in the TZ database. Problem is: what is the "county of Yancowinna"? The Australian Standard Time Act 1987 mentions this county, but doesn't mention the county boundaries. Once they were known, but they have disappeared from recent maps. Finally I found a scan of an old map from the Land Registry, showing the Yancowinna county. Found on the website of The Sydney Morning Herald: <http://www.smh.com.au/articles/2003/08/29/1062050651816.html?oneclick=true> Click on field number 2 or download the map directly: <http://www.smh.com.au/specials/leases/pdf/map2.pdf> The following places are within the county boundaries: Broken Hill, The Gorge, Mount Gipps, Silverton, Stephens Creek, Wahratta, Yanco Glen. The name "Wahratta" is not perfectly readable from the map, but I've checked the name and location against the Australia file from the GEOnet Names Server <http://earth-info.nga.mil/gns/> Oscar van Vlijmen 2005-04-23

Fix for Azerbaijan daylight saving rules
by Rustam Aliyev 23 Oct '05

23 Oct '05

Dear tz team, I would like to report that the time of daylight saving for Azerbaijan is incorrect in current version of tz. In the latest version of tz, both rules become effective at 1:00am. According to the resolution of the Cabinet of Ministers on daylight saving in the territory of Azerbaijan: 1. Inasmuch as every year since 1997 all clocks are advanced one hour at 4am on the last Sunday of March, Azerbaijan Republic must pass to summer time. 2. By turning clocks back an hour at 5am on the last Sunday of October, summer time is cancelled. Full text of resolution in English and Azeri is available at: <http://aif.az/docs/daylight_res.pdf>. Original images of resolution will be added to this document later. This document is effective since March 1997. Thus, daylight saving rule for Azerbaijan should be: -------------------------------------------------------------------- # Azerbaijan # Rule NAME FROM TO TYPE IN ON AT SAVE LETTER/S Rule Azer 1997 max - Mar lastSun 4:00 1:00 S Rule Azer 1997 max - Oct lastSun 5:00 0 - -------------------------------------------------------------------- Find attached diff file for asia with proper changes against tzdata2005n.

Re: Daylight Saving Time in Brazil

Ronaldo Vasconcellos <ronaldo(a)cais.rnp.br> writes: > http://www.tldp.org/HOWTO/TimePrecision-HOWTO/tz.html#tz.examples [I'll CC: this message to Avi Alkalay, who maintains that web page, so that he can correct its time zone abbreviations as he sees fit.] As far as I can see, the abbreviations used in the above-referenced table are merely examples and are not meant to be recommendations. Abbreviations like "BRDT" would not correspond to common Brazilian practice, which is to use the Portuguese equivalent of "summer time" rather than "daylight time". As is stated in the tz tables' comments, in 1999 I invented the abbreviations BRT/BRST, AMT/AMST, etc., that are used in the current tz tables for Brazil. As far as I know nobody else has needed, or uses, English-language acronyms for the Brazilian time zone. However, should an alternate tradition arise in practice, of course we'd prefer to use the English-language abbreviations that people are actually using, as opposed to abbreviations that we have invented.

However, Indiana will observe DST next year, so we probably should stop equating Indianapolis with "no DST". Also, in reviewing the comments, they need updating in the light of the current US plans for DST, and I found the first line a bit confusing. How about the following further patch? It attempts to address these issues. Does anyone know when the SystemV rules were written? If so, that "1976" below should be changed to that date. It had to be some time in the 1976/1987 time frame. --- systemv 2005/10/03 13:56:37 2001.1.0.1 +++ systemv 2005/10/04 04:31:57 2001.1.0.2 @@ -1,10 +1,10 @@ # @(#)systemv 7.4 -# Old rules, should the need arise. +# The commented-out entries below contain old rules, should the need arise. # No attempt is made to handle Newfoundland, since it cannot be expressed # using the System V "TZ" scheme (half-hour offset), or anything outside # North America (no support for non-standard DST start/end dates), nor -# the change in the DST rules in the US in 1987 (which occurred before +# the changes in the DST rules in the US after 1976 (which occurred after # the old rules were written). # # If you need the old rules, uncomment ## lines and comment-out Link lines. @@ -42,7 +42,7 @@ Link America/Denver SystemV/MST7MDT Link America/Los_Angeles SystemV/PST8PDT Link America/Anchorage SystemV/YST9YDT Link America/Puerto_Rico SystemV/AST4 -Link America/Indiana/Indianapolis SystemV/EST5 +Link America/Panama SystemV/EST5 Link America/Regina SystemV/CST6 Link America/Phoenix SystemV/MST7 Link Pacific/Pitcairn SystemV/PST8
