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 up until the current law 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.

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.
