compiling backzone file with zic - How to?
by Alois Treindl June 28, 2019

June 28, 2019

I am trying to compile the zonefiles with zic, and I want to include the backzone file. I expect that zoneinfo/Africa/Mbabane comes out differently from zoneinfo/Africa/Johannesburg because in backzone there is # Eswatini (formerly Swaziland) Zone Africa/Mbabane 2:04:24 - LMT 1903 Mar 2:00 - SAST (Swaziland did not observe South African DST in 1942-1944 and I want to see that respected in the binary zonefile Africa/Mbabane) while in file africa there is: # South Africa # Rule NAME FROM TO TYPE IN ON AT SAVE LETTER/S Rule SA 1942 1943 - Sep Sun>=15 2:00 1:00 - Rule SA 1943 1944 - Mar Sun>=15 2:00 0 - Zone Africa/Johannesburg 1:52:00 - LMT 1892 Feb 8 1:30 - SAST 1903 Mar 2:00 SA SAST Link Africa/Johannesburg Africa/Mbabane # Eswatini I use the command: ./zic -d ./tzdata/etc/zoneinfo africa antarctica asia australasia backward backzone etcetera europe factory northamerica pacificnew southamerica systemv and expect the information in 'backzone' to override the information in 'africa'. But it does not. These two files are generated but are binary identical. zoneinfo/Africa/Mbabane zoneinfo/Africa/Johannesburg What is the correct command line for zic so that information in backzone is considered? I have tried putting backzone at he begin or end of the list of files, but that made no difference in the binary output.

Summer Time Brazil 2019 - Information
by Walmir Tadeu Satyro June 27, 2019

June 27, 2019

Good Afternoon, I need to know if there is an update of TzUpdater for the Brazil region in 2019. Today we need to validate if there is or was something specific to update here in Brazil. We understand that this is usually time consuming ... It is a question of updating the product and in it is contemplated specific rules for each region not only Brazil As we did not have defined summer schedules there were no corrections issued by IANA regularly, they are valid internationally since it is the Java product. To check if there is a most recent Brazil update in case of summer time 2019 Best regards.

Petition to abolish local time in Sommarøy, Norway
by Paul Eggert June 26, 2019

June 26, 2019

On Thursday, Kjell Ove Hveding, who lives in Sommarøy, Norway (latitude 70°N, population 321), formally petitioned his parliamentarian to abolish civil time in the town. Assuming this becomes law and common practice (which does not appear likely), I suppose we'd need to create a new entry for the region of Norway that switches to having no civil time whatsoever. (The tzdb convention for this is UTC with the abbreviation "-00".) The Gizmodo story about this quotes Hveding as saying: "You have to go to work, and even after work, the clock takes up your time. I have to do this, I have to do that. My experience is that [people] have forgotten how to be impulsive, to decide that the weather is good, the Sun is shining, I can just live." See: Mandelbaum RF. A Norwegian city wants to abolish time. Gizmodo. 2019-06-14 16:55 -04. https://gizmodo.com/a-norwegian-city-wants-to-get-rid-of-clocks-1835526377

Precise meaning of AT 25:00
by Stephen Colebourne June 26, 2019

June 26, 2019

The Tokyo rule now includes the value 25:00 in the AT column. Can someone confirm the exact meaning of the 25:00? Is it a) an extended local time-of-day b) the actual duration from midnight at the start of day While similar, there would be a difference between the two definitions if there was a second DST gap/overlap earlier in the day. eg. imagine the case where DST starts at 13:00 (with a gap to 14:00) and ends at 26:00. With (a) the AT column would hold 26:00, while with (b) the AT column would hold 25:00 I'm pretty sure it is (a), but wanted to double check before it gets baked into APIs Stephen

*Off top* A little respect ...

Actually, I disagree, that is *EXACTLY* what this list is about. It is a *technical list about timezones* and the IANA TZ software. Generally, I/we would rather politics did not rear its ugly head. However, there is a constant trickle of folks *WHO MISS THIS POINT ENTIRELY*. > The question is, to which country belongs the territory occupied by Putin Huilo. To you; perhaps. To this list, probably not. *County codes* kept by the TZ database are a secondary aspect of the zone. (Again: *NOT A LEGAL DOCUMENT*.) TZ keeps the country code only as a non-authoritative aspect of the data. Specifically, "the CC normally identifies the administrative hierarchy that currently effectively determines the the civil time". Again, we're talking about "reality on the ground". (Though Dr. Eggert did mention AQ (Antarctica) and Crimea being exceptions.) "zone.tab", one of the files listing CCs, explicitly states: 19: This table is intended as an aid for users to help them select timezones 20: appropriate for their practical needs. It is not intended to take or 21: endorse any position on legal or territorial claims. "zone1970.tab", the other file, says exactly the same thing starting on line 30. Both files explicitly refer to this disclaimer for the Europe/Simferopol entry. Last but not least, currently the CCs of Europe/Simferopol in ".zone.tab" and "zone1970.tab" are "UA" and "RU,UA" respectively. These seem apropos to me.

Yes, I suppose that might have pleased Putin (if he ever became aware of it if only by the fact that his cellular telephone showed the correct local time) but ... it wasn't done to please or displease him or his cronies (and the fifth columnists 'phones are right, too.) It was, as has been explained, to reflect the technical "reality on the ground". I'm sorry if that displeased you but it is what it is. Being obstreperous isn't going to change anything (except by further expanding the misery). Making us out to be tools of injustice doesn't make it so. Note that the *country codes* that came into question have been patched reasonably expeditiously by Dr. Eggert. TZ will reflect reality as best it can under the circumstances with or without anyone's complete satisfaction. I *am* certain that no one is happy about all the death, destruction and heart wrenching circumstances from what has come to pass. My thoughts and prayers are with all the people who find themselves in such unfortunate conditions. Were it only within my power to change them....
