[PATCH] * asia: Correct Hong Kong section name.
by Jimmy Yuen Ho Wong Dec. 18, 2019

Dec. 18, 2019

There are no records of Hong Kong being referred to as Xianggang, in the past or currently. The Pinyin romanization scheme of the Mandarin pronunciation of 香港 is not officially recognized or even mentioned in official documents. https://www.basiclaw.gov.hk/en/basiclawtext/chapter_1.html https://www.elegislation.gov.hk/hk/cap5 --- asia | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/asia b/asia index cca004f..4f19d14 100644 --- a/asia +++ b/asia @@ -572,7 +572,7 @@ Zone Asia/Urumqi 5:50:20 - LMT 1928 6:00 - +06 -# Hong Kong (Xianggang) +# Hong Kong # Milne gives 7:36:41.7; round this. -- 2.24.0

isdst bug Europe/Dublin (tzdb-2019c)
by Stefan Rueger Dec. 16, 2019

Dec. 16, 2019

Looks like zdump claims Dublin has DST during winter, not summer: $ ./zdump -i -c2020,2021 Europe/Dublin TZ="Europe/Dublin" - - +00 GMT 1 2020-03-29 02 +01 IST 2020-10-25 01 +00 GMT 1 Compare with the output for London, which is as I would expect: $ ./zdump -i -c2020,2021 Europe/London TZ="Europe/London" - - +00 GMT 2020-03-29 02 +01 BST 1 2020-10-25 01 +00 GMT Generally, I think it's neater if the time stretches with the larger GMT values are considered DST. This is almost always true, except for Europe/Dublin, Eire, Africa/Casablanca and Africa/El_Aaiun. Morocco (and Western Sahara) change the time to have shorter fasts during Ramadan, so to speak to *not* save daylight. I would therefore still argue that the time outside Ramadan should be considered DST and the time during Ramadan the non-DST time. I am aware that the view "DST means larger GMT value" is not a precise definition (a region that change times zones in quick succession might easily accrue more than two GMT values within a few years). It's therefore not a great candidate for implementation in zic/zdump. However, I hold that periodic *future* annual back-and-forth switches should adopt that principle. Anyway, over to you Stefan PS: You are providing an *amazing* service - many thanks for that!

EU and Brexit Time Borders
by Brian Inglis Dec. 12, 2019

Dec. 12, 2019

EU member states get to decide whether to stay on summer or standard time: https://www.independent.ie/business/brexit/meps-vote-to-end-daylight-saving… What will Ireland do, and will Ulster follow Irish or UK time? https://www.independent.co.uk/news/uk/politics/brexit-irish-border-time-clo… Will UK follow, staying on GMT or BST, or keep switching? https://www.rospa.com/media/documents/road-safety/consultation-responses/di… "Under the new legislation, governments opting to make summer-time permanent would adjust their clocks for the last time on the last Sunday in March 2021. For those choosing permanent standard time, known as permanent winter-time, the final clock change would be on the last Sunday of October 2021." -- Take care.

Anticipated strategy for handling US state DST rule changes
by Marc Sackeli Dec. 12, 2019

Dec. 12, 2019

I apologize if this is a repeat question, but this question pertains specifically to how the tz database might change if individual US states start adhering to their own DST rules. There has been a wave of legislation <https://en.wikipedia.org/wiki/Daylight_saving_time_in_the_United_States#201…> coming from individual states trying to shift towards a year-round DST model. While several states have successfully passed this legislation, their ability to shift is reliant on federal approval. Arizona has been able to drum to their own beat on DST, and I don't think it's far fetched to think other states might be allowed to do so in the future as well. If this is a potential outcome, is there an idea of how the tz database would adapt to this change? My guess is that new entries would be created to allow us to delineate between these states. We are currently covered if California decides to change thanks to America/Los_Angeles, but what if Oregon or Tennessee decides they want to change? Does this mean America/Portland and America/Nashville would be created? Or perhaps America/Oregon and America/Tennessee? Any thoughts would be appreciated. -Marc

Iceland may move from +00 to -01
by Paul Eggert Dec. 11, 2019

Dec. 11, 2019

Since 1968 Reykjavík has been about 1.5 hours ahead of mean solar time. The government of Iceland recently asked people which of three things they wanted to do about this, and the survey results were: 4% - educational campaign to encourage people to go to bed earlier 37% - leave the clocks alone 56% - change from +00 to -01 The prime minister's office is drafting a bill to implement the majority opinion: this would undo the 1968 change from -01/+00 (with DST) to permanent +00, and would revert to permanent -01, which was observed 1908-1916 and 1922-1938. Although I've seen many proposals from around the world to change the clocks, this bill seems to have a real chance of passing so I thought I'd give the list a heads-up. My source: Fontaine A.
