Antarctica/Troll time
by Phake Nick Nov. 18, 2019

Nov. 18, 2019

In the Antarctica file of tz database, some rules for Antarctica/Troll have been commented out, with the description of it saying "uncomment them when 2014b is more prevalent". Is it still not prevalent enough to uncomment them now?

UK Lords "Discontinuing seasonal changes of time" publications
by Paul Eggert Nov. 14, 2019

Nov. 14, 2019

The EU Internal Market Sub-Committee of the UK House of Lords has published oral and written comments on proposals to abolish DST transitions in the UK, and are preparing a report. The main comment that caught my eye was from Google's Jonathan Skeet <https://data.parliament.uk/writtenevidence/committeeevidence.svc/evidencedo…>. Skeet underscores the utility of announcing changes long in advance. He goes into considerable detail about "Europe/London" and other tzdb names, negative DST in the Republic of Ireland, "permanent" DST, "BST" and other time zone labels, and so forth. The complete list of published comments can be found here. This list contains a copy of the comment that I circulated on the tz mailing list on August 5. https://www.parliament.uk/business/committees/committees-a-z/lords-select/e…

Change DTS and time zone for Morocco
by liuchao (CR) Nov. 12, 2019

Nov. 12, 2019

In the past, Morocco observed four clock changes per year. Like in most other countries with seasonal time changes, the DST period in Morocco started in the spring and ended in the fall (autumn). However, clocks were turned back to standard time during the Islamic month of Ramadan to make it easier to observe the daytime fast. The Kingdom of Morocco now remains permanently set to UTC+01:00 instead of following an earlier plan to return to UTC+00:00 on October 28, 2018. But the data in Africa doesn't change. There still are four clock changes in 2018, which causes isdst flag error in 2019. https://support.microsoft.com/en-us/help/4468323/dst-and-time-zone-changes-… https://www.timeanddate.com/news/time/morocco-abolishes-time-changes.html Before change, [cid:image001.png@01D59979.EB9BDA90] on May 5 2019, the time jumps from 02:59:59 to 02:00:00, the isdst flag should change from 1 to 0. After change, [cid:image002.png@01D59979.EB9BDA90] When dataform is rearguard, it is fixed via ziguard.awk, [cid:image003.png@01D5997A.49F01BB0] However, I don't understand why it's only changed in rearguard format.

Changes in daylight saving rules in Brazil
by Alexandre Henrique Soares Dias Nov. 6, 2019

Nov. 6, 2019

Dear IANA Team, My name is Alexandre Dias and I'm a Data Scientist at a Brazilian Startup called Looqbox. As an R programmer and knowing that R uses the international standard IANA time zone rules. I would like to inform that the current Brazilian government changed daylight saving rules for "America/Sao_Paulo" timezone. This changes occurred this year and many devices are operating under the wrong hour of the day. Usually, at this time of the year we had to advance our clock by one hour going from -03 GMT to -02. However, as I said, this is no longer the rules and the clocks must remain -03 GMT. Following there is a print of this phenomenon showing that R is display and returning the wrong time for my timezone: [image: image.png] <https://files.slack.com/files-pri/T0NA05E3Y-FQ4LFH6CV/image.png> The correct output should be "2019-11-04 13:25:27 -03". Given the problems that may arise from this kind of behavior, I kindly ask you to apply the changes I informed above as soon as possible. Sincerely yours, Alexandre Henrique Soares Dias Data Scientist at Looqbox

No more DST in Brazil
by Sergio Leal Nov. 4, 2019

Nov. 4, 2019

Dear Sirs, I am a PHP programmer and I verified a problem when I setted a timezone location to "America/Sao_Paulo" for a program. I observed that data was showing dates and times with 1 hour difference. After some search, I downloaded the TZ database from https://www.iana.org/time-zones/repository/tzcode-latest.tar.gz where I believe that Brazilian DST remains setted, despite of Brazilian Governament has officialy cancelled DST in Brazil as described in the file southamerica finded in the TZ database in lines 946 to 949. I hope I could help. Regards, Sergio Leal Enviado do Email para Windows 10

Potential problem with Sao_Paulo TZ in tzdata2019c
by Bryan Coleman Nov. 1, 2019

Nov. 1, 2019

It appears there is a bug with the America/Sao_Paulo time zone; specifically, with the 2014-02-15/16 DST change. Not sure the best way to confirm and/or if there is someone that can quickly check/verify. Thoughts? I found this while working with java and noticed it after upgrading from adoptopenjdk version 8u222_b10 to version 8u232_b09. I believe 222 utilizes tzdata2019a while 232 utilizes tzdata2019c. I understand that there are many things that could cause the issue from the code running in java down the stack to the tzdata; however, believe tzdata is the most likely culprit. Any thoughts/ideas of how to track this down?
