I received this document, which claims DST from 2 August 1980 - 13 Sept 1980 and 5 May 1984 - 25 August 1984. These two periods are not contained in the current TZ database, which has Rule Zion 1974 only - Jul 7 0:00 1:00 D Rule Zion 1974 only - Oct 13 0:00 0 S Rule Zion 1975 only - Apr 20 0:00 1:00 D Rule Zion 1975 only - Aug 31 0:00 0 S Rule Zion 1985 only - Apr 14 0:00 1:00 D Rule Zion 1985 only - Sep 15 0:00 0 S Rule Zion 1986 only - May 18 0:00 1:00 D Rule Zion 1986 only - Sep 7 0:00 0 S -------- Forwarded Message -------- Subject: Hello to astro system Date: Tue, 18 Sep 2018 03:18:57 +0300 From: Israel Tzaig <israheal@gmail.com> To: order@astro.ch <order@astro.ch> My name is Israel Sagi and I wanted to update you about daylight saving time in Israel. In 1980 there was a summer time from 3.8 to 13.9. This clock is not updated on your maps. Attached is a page from the Ministry of Interior for daylight saving time in Israel Thank you and hope you will use the information here. For a double check, I went to the archives of Yedioth Ahronoth (the most popular newspaper in Israel) in 1980 to make sure that there was a daylight saving time. I would be happy to send you a photo of the relevant articles (in Hebrew of course) נשלח מהאפליקציה 'דואר <https://go.microsoft.com/fwlink/?LinkId=550986>' עבור Windows 10
Thanks for the info; we'll need to update tzdata. That document looks out-of-date, though, as it surely isn't correct for transitions after the year 2012. I attempted to find a more up-to-date version which tzdata could cite, and found this: https://web.archive.org/web/20160322110509/http://www.moin.gov.il/Publicatio... but I would rather cite a web page that's currently maintained by the Ministry of Interior. Is something like that available? Unfortunately I don't know Hebrew so my searching abilities are limited. Thanks for any help or advice you can provide in this matter.
On the Ministry of Interior's "summer time 2018" page, there is a link to the following chart: http://www.moin.gov.il/Documents/%D7%A9%D7%A2%D7%95%D7%9F%20%D7%A7%D7%99%D7%... Which contains the same dates in Paul's link, but a different rule for the start of DST from 2013 onwards. Paul's document does not have the rule from 2013 onwards and incorrectly states the 2012 DEST-start rule as "the Friday before the last Friday (sic) of March"; the second documents states for 2012 and for 2013 onwards the DST-start rule as simply "the last Friday in March". Both are wrong. The current rule (since 2013) is "the Friday before the last Sunday in March" -- reference: ftp://ftp.cs.huji.ac.il/pub/tz/announcements/2013+law.pdf Furthermore, Paul's document correctly states the November 2012 start rule as "the first Sunday after October 1st" -- this rule was never implemented since the law was changed in July 2013. The currect document has it as "the first Sunday before the 10th of the [Hebrew month] of Tishrei [i.e. the Sunday before Yom Kippur]" -- reference: ftp://ftp.cs.huji.ac.il/pub/tz/announcements/2012+draft.pdf Hence, while the best that we currently have, Ministry of Interior historical announcements should be taken with a grain of salt. What officially marks the dates of DST start/stop is the Knesset Registrar ("Reshumot"). I have put it on my bucket list for my retirement years to check the accuracy of the Ministry of Interior dates also by viewing old newspaper archives at Israel's National Library.

In theory we could change the last spring-forward Rule line for Zion from "Mar Fri>=23 2:00" to "Mar lastSun -46:00" to try to capture this rule more precisely. However, as the two strings are equivalent, neither captures the original rule precisely, and the "-46:00" is more likely to trip up non-zic parsers, it's probably better to leave it alone.

That would be helpful, thanks. For the case of 1980, Israel Sagi has already checked the archives of Yedioth Ahronot. Israel, could you please send us a photo of the relevant article or articles? Thanks.

I still have a few years before retirement though ... In the meantime, I have have downloaded from the Knesset archives, the various addendums and changes to the Time Determination Ordinance that has its origins in 1940 during the British Mandate <ftp://ftp.cs.huji.ac.il/pub/tz/laws/May_22_1940.pdf> up until the current law <ftp://ftp.cs.huji.ac.il/pub/tz/laws/Jul_11_2013.pdf> and placed them all under ftp://ftp.cs.huji.ac.il/pub/tz/laws/ -- all files are in Hebrew. Basically, from 1940 until 2004, the start/end times of DST was determined by the Minister of Interior and a set rule for the times was only first passed as a law in 2005 which was amended in November 2012 and then again in July 2013.
