Question] Regarding Asia/Yerevan timezone abbreviation
by Goun Lee Sept. 10, 2020

Sept. 10, 2020

Hi, I'm Goun from South Korea. I have a question regarding Asia/Yerevan timezone abbreviation When I checked the following line, https://github.com/eggert/tz/blob/master/asia#L127 it's written as 4:00 Armenia +04/+05 As far as I know, Armenia has no DST time, so the abbreviation should +04. isn't it? I'm just wondering if it's correct or not. best regards. Goun

timezone DB distribution
by Juergen Naeckel Sept. 8, 2020

Sept. 8, 2020

Hey there, First of all, I would like to thank you. I have to implement something in JavaScript that uses timezones. However, I am using an older JS version that does not have the flexibility like today’s JS. So I was looking for a repository holding all current timezones and rules for it, rather then me, checking time and again how which timezone is configured 😉 This really could help me. Reading through the files, it sometimes made me chuckle and I was actually surprised how fluent timezones are handled. Changes almost every year… I would like to recommend some improvements. I know you have pretty stable release by now. I am aware that changes probably to the structure might affect a lot of people/projects. However… First of all, a tar.gz is Linux specific. True, you could install additional Windows software. But, that might not go well with customers of mine. I think a ZIP would be acceptable for both worlds. Since I was interested in the repository, I downloaded the “Data only distribution”. I found six files containing the TZ information. And I found 27 files, containing other stuff. Well, there might be three or four files in a grey zone (calendars, backlist…). But I definitely do not consider MAKEFILE and .awk file as part of a “data only distribution”. Maybe move them to a separate folder in the GZ file? Finally, I got one more recommendation/question. I had read the readme file but it didn’t explain the data I saw in the files. It took me a while to understand the concept of the data structure. Some info of what to see in the file, and how to read it would help. And I think the first line of the ZONE definition contains some inconsistency (maybe I still didn’t understand it correctly). Below is a screenshot. See the first line for the zones? It looks mismatched with the New York. The RULE and the [UNTIL] are probably in the wrong column. Format is probably missing. [cid:image002.png@01D674A5.27F71B60] Then I noticed that the open-end validity. For rules it is denoted as “max” and for zones it is just a <blank>. Could we get some consistency here? And finally here comes my question: In the rules, I see in the column several times denoted with a tailing “u” or “s”. I think I read on one occasion that the times are denoted in “standard time”. I do not recall anymore where that was. But regardless, 1. I don’t understand what that “denoted in standard time” would mean 2. I definitely have no clue would the tailing “u”: would imply. [cid:image003.png@01D674A6.99550F50] Can you shed some light on this? Thank you! Not only for an answer but also for researching and compiling this list.

Iceland stays put on time zone
by Paul Eggert Sept. 7, 2020

Sept. 7, 2020

After more than two years of discussion, Iceland's government decided not to move its time zone back to -01, where it was before daylight saving time was introduced. Currently Iceland is at +00, effectively permanent DST. Proponents of changing back had argued that DST has harmful effects on human health. To counteract DST's health effects, the government decided instead to launch an educational campaign to get Icelanders to sleep more. It is also considering monitoring children's sleep habits and starting school days later. See: Gréta Sigríður Einarsdóttir, Iceland’s Time Zone to Remain Unchanged.
