Asia rules change
by Oleksii Nochovnyi March 28, 2014

March 28, 2014

Hi there! I'm agree with this comment in asia rules file: # From Phil Pizzey (2009-04-02): # ...I think I may have spotted an error in the timezone data for # Jordan. # The current (2009d) asia file shows Jordan going to daylight # saving # time on the last Thursday in March. # # Rule Jordan 2000 max - Mar lastThu 0:00s 1:00 S # # However timeanddate.com, which I usually find reliable, shows Jordan # going to daylight saving time on the last Friday in March since 2002. # Please see # <a href="http://www.timeanddate.com/worldclock/timezone.html?n=11"> # http://www.timeanddate.com/worldclock/timezone.html?n=11 # </a> It's real that Jordan makes transition to DST on last Friday of march. For this reason I've changed 2 rules Rule Jordan 2000 2001 - Mar lastThu 0:00s 1:00 S Rule Jordan 2014 max - Mar lastThu 24:00 1:00 S To Rule Jordan 2000 2001 - Mar lastFri 0:00s 1:00 S Rule Jordan 2014 max - Mar lastFri 24:00 1:00 S I'va attached my copy of changed file.

Re: [tz] Ukraine 1990
by Bogdan Krusiński March 28, 2014

March 28, 2014

Hello, http://search.ligazakon.ua/l_doc2.nsf/link1/T217600.html excuse us for the earlier confusion, the text from 11 june 1990 we sent was reotroactively decreed in 1992 to remove the words "Moscow time minus 1 hour". The version we sent was version after retroactive edition of 1992 year after decree ordering to remove these words was issued. The original Original text from June of 1990 was: "1. Установити з 1 липня 1990 року на території Української РСР час другого часового поясу без додання однієї години, московський час мінус одна година." "1. Introduction from 1st of July 1990 on territory of Ukrainian SSR time zone of two hours without summer time, Moscow time minus 1 hour". with best regards Bogdan Krusinski -----Original Message----- From: Bogdan Krusiński Sent: Sunday, March 16, 2014 12:47 AM To: 'tz(a)iana.org' Subject: Ukraine 1990 Hello, the contenst of decree at http://search.ligazakon.ua/l_doc2.nsf/link1/T001500.html contain only one point: "1. Установити з 1 липня 1990 року на території Української РСР час другого часового поясу без додання однієї години." "1. Intorduction from 1st of July 1990 on territory of Ukrainian SSR time of two hours without addition of one hour". I'm a bit disturbed because I was directed by astro.com to these archives where it is translated as: "Set on 1 July 1990 in the Ukrainian SSR, the second time zone with the addition of one hour." "without" is not "with". Pozdrawiam serdecznie Bogdan Krusiński

hello first background the Question is last i just spent an hour trying to edit America/New_York only to find US had been changed my two hosts disagreed by 1 hr and daylight savings time but not UTC prev US section used "max". apparently (i dont' have all tz revisions) someone change the last US rule this changes assumptions made in all rules of states using US in their Rules meaning one host assumes NY follows US from (19xx) forward, so does the other: but since US chaned they are an hour off -------------------------------------- Question: why was that a good idea ? and what if new Rules file becomes incompat with my libc and i cannot zic/compile and load "new localtime assumptions" ?? it seems rediculous however i'm guessing there is a good answer
