?Hello, We're writing you on behalf of Russian software developer - Nexign, and all of its clients. Your IANA DB is used in our products as an industrial standart. The reason of this email is that Russian government is about to decide to change the Europe/Volgograd timezone from +4 to +3. This is going to affect our software and our customers, so we would like to know: 1. Are you aware of this changes? 2. Has the patch of IANA DB been planned already?

Ontario moving to permanent DST? Perhaps someday.
by Tim Parenti Dec. 5, 2020

Dec. 5, 2020

The Legislative Assembly of Ontario has passed a bill which would advance standard time in the province by one hour and repeal the seasonal clock changes — effectively putting the province on year-round daylight saving time. https://globalnews.ca/news/7485079/ontario-daylight-saving-time-amendment-a… According to MPP Jeremy Roberts, who introduced the private member's bill, the legislation would require "coordination" with neighboring jurisdictions such as Quebec and New York state, and "would not come into effect until the Attorney General decides it should come into effect." Indeed, the text of the bill states that the act "comes into force on a day to be named by proclamation of the Lieutenant Governor", who represents the Canadian monarch. The bill passed the assembly unanimously on its third reading and received Royal Assent on 30 November 2020. https://www.ola.org/en/legislative-business/bills/parliament-42/session-1/b… https://www.ola.org/sites/default/files/node-files/bill/document/pdf/2020/2… -- Tim Parenti

Some time zone history (1)

> The Determination of the Time Ordinance, 1919 commenced on 1919-11-24. Thanks for catching my typo; proposed patch attached and installed into GitHub. > Also, the Defence (Revocation) (No.4) Regulations, 1945 commenced on 1946-01-06. True, but how would that affect tzdb? As I understand it, those regulations <https://books.google.com/books?id=9as-AQAAIAAJ&pg=PA256> repeal DST, but on 1946-01-06 Gold Coast was already on standard time (having switched from DST on 1946-01-01). Hence on 1946-01-06 there was no clock transition, merely a change in which regulation was in force.

Nov. 30, 2020

Hello, How is it possible to get the timezone for a specific datetime and a (ISO3166-1 alpha2, ISO3166-2) pair, i.e. a country code + region code ? Example: ISO3166 -> TimezoneDE-BE -> Europe/Berlin AU-TAS -> Australia/Hobart or Australia/Tasmania US-NY -> America/NewYork Thank you in advance,Jo PS: I have seen the file "iso3166.tab" but this is only for country codes, i.e. the first part of ISO3166.

Time zones in conflict areas

It looks like your base has inadvertently become a hostage to politics. Theoretically, your point of view should coincide with UN resolutions. It says that Russia temporarily occupied Crimea. And this territory is still considered Ukrainian. You can find evidence on the google => “site:undocs.org crimea occupation”. I found the following information in your database: # From Alexander Krivenyshev (2014-03-17): # time change at 2:00 (2am) on March 30, 2014 # https://vz.ru/news/2014/3/17/677464.html # From Paul Eggert (2014-03-30): # Simferopol and Sevastopol reportedly changed their central town clocks # late the previous day, but this appears to have been ceremonial # and the discrepancies are small enough to not worry about. 2:00 EU EE%sT 2014 Mar 30 2:00 4:00 - MSK 2014 Oct 26 2:00s 3:00 - MSK The source of your time change data comes from the occupying country. Unreliable source. Can you tell me the reasons for your decision? And don't you plan to correct this mistake? Do you have evidence of the legitimacy of the government that changed the time zone in the conflict area?

> The major problem is that lazy programmers simply list the tz id's as if > they are all that is available. Adding extra id's will just result in both > being listed and then one gets even more complaints? Would it help if there was a translation file readily available? I'm picturing one for each language or country or whatever. The idea is to distribute them with the tz data so that individual programmers that want to do the right thing and use appropriate names rather than file names in their UI don't have the excuse that the data isn't available. The problem then becomes who decides what goes into the table. I see several options. One is to use some official government source, USGS or State Dept in the US. Another would be to find a trusted volunteer (or team) for each file. How much of the raw data is available online already? Would such a file be easy to maintain if there was a URL pointing to the source. (The idea is to avoid discussions like Kiev/Kyiv.) -- These are my opinions. I hate spam.
