Thanks very much for all that work. I found only a couple of typos. First, the 
line beginning with "2000 Temporary Provisions" should end with 2000-10-06 not 
2000-09-06. Second, citation 3 should be 
https://findit.library.yale.edu/images_layout/view?parentoid=15537491&increment=721 
instead of the same URL ending in "=958".

I ran into several ambiguities, where a transition at “midnight” might have been 
at 00:00 or 24:00, and might have been at standard time or daylight saving time. 
When resolving these ambiguities, I attempted to minimize the changes from 
existing tzdb. Most likely some errors remain, but still we should be better off 
than we were before.

I installed the attached proposed patch to implement this. It reformats your 
file to fit into 80 columns when included as a comment. There are so many 
changes I didn't detail them all in NEWS, and I removed similar detail from 
Kenya news to be consistent.

To give people a feel for the timestamp changes involved, I am also attaching 
the output of "diff -U4 to2050.tzs to2050new.tzs". This lists all changed 
timestamps. The columns are date, hour of day, UTC offset, abbreviation, and 
tm_isdst flag, with all columns (including hour) being in effect just *after* 
the transition.

Subject: [PROPOSED] Fix Israel and Palestine transitions 1940/1985
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Fix several transitions from 1940 through 1985, and supply
legal citations for the fixes.  (Thanks to P Chan.)
In some cases we are still guessing what “midnight” means.
* NEWS: Mention this.
* asia (Zion): Fix several transitions.
Also, improve citation to current law
(thanks to Ephraim Silverberg).

-    Insert a transition from LMT to +0230 on 1908-05.
-    The first transition to +03 was on 1928-06-30, not 1928-07.
-    The later transition to +0230 was on 1930-01-04, not the guessed 01-01.
-    The transition to +0245 was on 1936-12-31, not 1940.
-    And the final transition to +03 was on 1942-07-31, not 1960.
