Hong Kong listed as UK not China
by Shelley Finerty March 15, 2022

March 15, 2022

Hi there, I was using a tool that allows me to look at people’s birthdate, time and location and noticed that you still have Hong Kong listed as part of the UK with throws off the timezone for their birthdate. I had to choose another city close to Hong Kong to use it correctly. Is this something that can be changed or updated? Or are you keeping it for historical purposes? Is there a way to do both? Thanks for keeping the time so accurately - I appreciate the work you’re doing. Shelley Finerty Canada

Re: [tz] Summer time
by heba.hamad＠mtit.gov.ps March 10, 2022

March 10, 2022

Dear sir, regarding to summer time for this year , the timing will be on 3/27/2022, but this does not necessarily mean that the change for the coming years will be on the same date. You will be provided with any new decisions about summer and winter times for the coming years and we will try to provide you with any changes more earlier than previous years. BR, في الخميس, مارس 10, 2022 14:26 EST, Paul Eggert <eggert(a)cs.ucla.edu> كتب: 3/04:50,http://www.palestinecabinet.gps/portal/Meeting/Details/51955 heba.hamad(a)mtit.gov.ps wrote: > We would like to inform you that the summer time will begin in Palestine from Sunday 03-27-2022 ,00:00 AM by 60 minutes forward. Thanks, do you have a URL for that announcement? It sounds like Palestine is changing its spring-forward rules, so that Palestine will now spring forward at 00:00 on the first Sunday on or after March 25, whereas during 2020 and 2021 Palestine sprang forward at 00:00 on the first Saturday after March 24. Is my understanding correct? Knowing the transition rule would be helpful, because TZDB makes predictions about future years, some computer applications rely on this (perhaps unwisely, but that's what they do), and the more accurate the predictions the better off everybody will be. This is related to Clive Feather's point that we need plenty of advance notice of rule changes (we'd like a year's notice). Without knowing the answers to the above questions, I installed the attached proposed patch into the TZDB development version. If possible, I'd like to improve this (based on answers to the above questions) before the next TZDB release, which should happen soon.

Jordan summer time zone is not updated in IANA database
by Abugharbieh, Raghad March 2, 2022

March 2, 2022

Hello I’m sure if you’re already aware of this or not , but in Jordan the timezone was changed on Thursday to meet summer changes. So currently , time zone in IANA database is behind the real time in Jordan by 1 hour . this is causing some time issues in websites that use IANA database. I’m sending this to check if there’s anything I can do to update the timezone for Jordan in the database to fix the root cause instead of handling the issues we have in a hacky way . Best regards , Raghad Abugharbieh

backzone Africa/Lubumbashi
by Alois Treindl Feb. 28, 2022

Feb. 28, 2022

In file backzone there is an entry for Africa/Lubumbashi # Democratic Republic of the Congo (east) Zone Africa/Lubumbashi 1:49:52 - LMT 1897 Nov 9 2:00 - CAT There are scarce sources for time zones of former Belgian Congo. My main source for its time zone history is Henri le Corre, Régimes horaires pour l'Europe et l'Afrique. He has for the eastern provinces of Zaire GMT + 1 between 1897 Nov 9 GMT + 2 since 1920 Apr 25. Shanks follows le Corre. As does Francoise Schneider Gauquelin in he book Problèmes de l'heure resolus pout le monde entier. I think this is sufficient reason to change the zone into Zone Africa/Lubumbashi 1:49:52 - LMT 1897 Nov 9 1:00 - WAT 1920 Apr 25 2:00 - CAT For the province of Kisangani, formerly Stanleyville, le Corre gives a transition from GMT +1 to GMT + 2 on 1935 Jun 14. But as this agrees with Lubumbashi after 1970, I do not expect the creation of another backzone entry for that. This task will be left for my private pre-1970 TZ extensions.
