Wrong entry for Israel tz information

March 8, 2014

Greetings, It seems we found an error in Israel DST transition for the year 1988. Please check if I'm right and correct me it I'm wrong. This is the current information for the year, the transition has happened according to this on Friday night, changing to Saturday. $ zdump -v Israel | grep 1988 Israel Fri Apr 8 21:59:59 1988 UTC = Fri Apr 8 23:59:59 1988 IST isdst=0 gmtoff=7200 Israel Fri Apr 8 22:00:00 1988 UTC = Sat Apr 9 01:00:00 1988 IDT isdst=1 gmtoff=10800 Israel Fri Sep 2 20:59:59 1988 UTC = Fri Sep 2 23:59:59 1988 IDT isdst=1 gmtoff=10800 Israel Fri Sep 2 21:00:00 1988 UTC = Fri Sep 2 23:00:00 1988 IST isdst=0 gmtoff=7200 I check the Parliament ( Knesset ) records and there it's stated that the transition should take place on Saturday night, when the Sabbath ends and changes to Sunday. The definition in the source file is as follows: Rule Zion 1988 only - Apr 9 0:00 1:00 D Rule Zion 1988 only - Sep 3 0:00 0 S Which result with the times above. When changing the source to be: Rule Zion 1988 only - Apr 10 0:00 1:00 D Rule Zion 1988 only - Sep 4 0:00 0 S And compiling it with zic we get $ zdump -v Israel | grep 1988 Israel Sat Apr 9 21:59:59 1988 UTC = Sat Apr 9 23:59:59 1988 IST isdst=0 gmtoff=7200 Israel Sat Apr 9 22:00:00 1988 UTC = Sun Apr 10 01:00:00 1988 IDT isdst=1 gmtoff=10800 Israel Sat Sep 3 20:59:59 1988 UTC = Sat Sep 3 23:59:59 1988 IDT isdst=1 gmtoff=10800 Israel Sat Sep 3 21:00:00 1988 UTC = Sat Sep 3 23:00:00 1988 IST isdst=0 gmtoff=7200 And the transition is as decided by the parliament on Saturday night toward Sunday. I also added the following lines to the source file Link Asia/Jerusalem Israel Link Asia/Jerusalem IST-2IDT Please check me out and if I'm right, correct the next release of the tzdata file. I don't know how many people and organizations are still interested in data from 1988, but the record should be set right. Thanks in advance. -- Best Regards, Avigdor ---- Email: AvigdorFin@g <Avigdor.Finkelstein(a)tangram-soft.co.il>mail.com ISRAEL

West Virginia broadcasters 1946 DST proposal
by Garrett Wollman March 8, 2014

March 8, 2014

Quoting from /Broadcasting * Telecasting/ of March 18, 1946: In a move believed to be unprecedented in radio, the newly-formed West Virginia Broadcasting Assn., comprising all stations in the state, will adopt daylight savings time form April 28 through Sept. 29 -- although West Virginia clocks will remain on standard time throughout that period. The time change was unanimously voted by the broadcasters at a meeting held in Charleston March 9. Representatives of all of the state's 14 stations agreed to the resolution. On March 12, all stations included the resolution in all newscasts. Under the plan, radio clocks will be changed to conform to network clocks [ed: the networks observed New York City time, which had DST in 1946] when time change occurs. This means that, unless the West Virginia legislature takes action to the contrary during a special session to be held in two weeks, West Virginians will have two time schedules -- that decreed by the state an that observed by radio. Time Announcements Participating stations will give time-announcements by the radio clock; they will make no rate adjustments, since their proposition is based on the assumption that West Virginia timekeepers are out of step with radio -- not vice versa. The article goes on to quote the full text of the resolution. -GAWollman

Re: [tz] Tennessee time

The video from the Tennessee state house of representatives where this bill was pitched can be found here (about 10 min long): http://tnga.granicus.com/MediaPlayer.php?view_id=269&clip_id=8600&meta_id=15 8484 "... you came up with a Wang Dangger!" - Rep. Johnny Shaw I believe Rep. Todd is mistaken in his assertion that staying on DST year-round would give more daylight to schoolchildren waiting at the bus stop in the morning. Wouldn't it actually work in reverse? -----Original Message----- From: tz-bounces(a)iana.org [mailto:tz-bounces@iana.org] On Behalf Of lennox(a)cs.columbia.edu Sent: Thursday, February 20, 2014 8:07 AM To: Arthur David Olson Cc: tz(a)iana.org Subject: Re: [tz] Tennessee time (was Web sites using recent versions of the tz database) On Wednesday, February 19 2014, "Arthur David Olson" wrote to "tz(a)iana.org" saying: > On Wed, Feb 19, 2014 at 7:49 PM, Zoidsoft <zoidsoft(a)gmail.com> wrote: > > Tennessee has proposed permanent daylight time: > > http://www.chattanoogan.com/2014/2/18/269932/ > Legislation-Making-Daylight-Savings.aspx > > > If this moves forward at the state level, things could get interesting. > The US Uniform Time Act lets states choose whether or not to make the > DST switch, but may not allow for permanent DST (which would, in > effect, be a time zone switch). > > "Full text - Daylight Saving Time - United States Law - 15 USC > 6(IX) (260-7)" > http://www.webexhibits.org/daylightsaving/usc.html > > A reminder: I am not a lawyer. > > @dashdashado In principle, Tennessee could simultaneously move to Atlantic time, and stop using Daylight Savings Time. I think the fact that they could choose to call their resulting UTC-4 time zone "EDT" rather than "AST" probably wouldn't be in violation of the Uniform Time Act (but I'm not a lawyer either). That said, the federal Department of Transportation (which apparently has jurisdiction over such things) hasn't allowed Maine to move to Atlantic Time, so the odds that they'd allow Tennessee to do so seem rather low. (If Maine does ever manage to move its time zone, naming its zone identifier is going to be an interesting challenge for the TZDB -- since "America/Portland" is rather unfortunately ambiguous...) -- Jonathan Lennox lennox(a)cs.columbia.edu
