May 2, 2011

Hi, I am Mahmoud from Egypt. I want to inform you that Egypt won't use daylight saving this year http://oldbagofcairo.blogspot.com/2011/04/no-daylight-savings-time-in-egypt… I am using Ruby on Rails for a web application and it is using your database for timezone calculations.

proposed time zone package changes (Egypt et al.)

April 21, 2011

Here are proposed changes to the time zone package; the executive summary: Makefile change GCC_DEBUG_FLAGS rule for more warnings africa Egypt abandons DST in 2011 (and forward) (thanks to Alexander Krivenyshev) localtime.c recode increment_overflow and long_increment_overflow to eliminate gcc warnings (thanks to Paul Eggert) europe eliminate doubled words (thanks to Jim Meyering) southamerica eliminate doubled words (thanks to Jim Meyering) The "africa" changes do affect time stamps in Egypt in 2011 (and forward).

FW: Clocks in Novosibirsk in 1957
by Olson, Arthur David (NIH/NCI) [E] April 20, 2011

April 20, 2011

I'm forwarding this message from Mark Brader, who is not on the time zone mailing list. Those of you who are on the list, please direct replies appropriately. --ado ________________________________________ From: Mark Brader [msb(a)vex.net] Sent: Wednesday, April 20, 2011 7:49 PM To: Olson, Arthur David (NIH/NCI) [E] Subject: Clocks in Novosibirsk in 1957 Here is an item I found accidentally on page 16 of the (Toronto) Globe and Mail for April 25, 1957, while I was searching online for another topic. I thought the members of TZ might be interested in the Novosibirsk part and amused by the rest. Please forward to the list if you think appropriate. I am not on the list; replies should be directed accordingly. I have not gone to the library to locate the cited article in Maclean's (a Canadian newsmagazine). There may be small errors due to the scan not being fully legible as well as my own errors in typing. # Only an Hour Apart # Clocks in Novosibirsk # Comparatively Simple # # by MAGGIE GRANT # # In a recent issue of Maclean's Magazine, Blair Fraser mentions the # plight of citizens of Novosibirsk, Siberia, who for 38 years have # had the clocks at the east end of their city one hour faster than # those of the west end. # # This is due to a time boundary running smack through the middle # of the city, and Mr. Fraser dubs the Novosibirskites the "world's # most patient people" for putting up with this situation for so long. # # Now, I sympathize with Siberian citizens on almost every count, # but I cannot shed any tears over this one. Having a city's clocks # exactly one hour apart for 38 years sounds like an ideal arrangement # to me. I'm certain that a normally intelligent person would take # no more than a few days to catch on to the time differential, # and surely any dunce would know which end of the city was which. # # Therefore, a western Novosibirskite, caught in the eastern end # of town, would in all probability do little more than glance at # a clock before exclaiming: # # "Zlug' Krztoxni ghow'. Qwetevinoff da gmuy zlot pzis ud gvenn!" # Which translated means: "By Jove! A quarter to eight! I must # hurry if I am to be home for dinner at seven!" # # Compared to this simple situation, consider the trials to which # I am subjected by the timepieces under my roof. # # There is the grandfather clock in the hall, for instance, a family # heirloom and a charming thing to look upon. But the poor old dear # has never recovered from the shock of being moved from Mother's # house to mine, and simply cannot keep itself going. I have long # ago written it off as a deadhead, but Mother is a tenacious soul, # and every once in a while she hopefully sets the pendulum in motion. # If she would only warn me on these occasions, I would not be so # alarmed when it suddenly bongs out some totally irrelevant hour. # # The Empire clock on the mantel, on the other hand, has a # delightfully silvery voice. It keeps accurate time, too, but is # addicted to flipping its minute hand into the fireplace at frequent # intervals. These occurrences are apt to go unnoticed until the # time is urgently needed to set other clocks, when the cry goes up: # "The hand! The hand! It's off again!" and all activity ceases # in favor of ash-sifting. The offending member, once retrieved, # is dusted off and replaced on the dial at the time we presume to # be correct, but which seldom is. # # Another horological eccentric hangs on the kitchen wall, an electric # model in perky red and white to match the decor. Unfortunately it # got knocked down one day, and although we put it all together as # best we could, it has observed none of the laws of Greenwich since. # # You can look at that clock one minute and it will point to 12:10, # but three minutes later, glancing at it again, you will discover # that it has moved on to 4:30. Never once have I caught it in the # act of whizzing from point to point, and this I regret, because # I am sure it would be a challenging experience. # # The other electric timepiece is immobilized once a week by # Mrs. Swallow, the charlady, who favors its especial wall plug # above all others for vacuum cleaning activities. # # Further undependables about the place are two travelling clocks that # run for 18 and 15 hours respectively, and a wristwatch that is good # for only 11. Under these circumstances, I consider it rather unfair # of people to call me Laggy Maggie. After all, I do the very best # I can by going from room to room, jotting down the various times, # adding them up, and then striking an average. Although I admit the # system is far from perfect, it's the best I've been able to devise. # # I wonder if somebody in Novosibirsk can offer a better one? -- Mark Brader, Toronto "Don't be silly -- send it to Canada" msb(a)vex.net -- British postal worker

Did Irkutsk NOT switch from IRKT to KRAST?
by Tim Parenti April 19, 2011

April 19, 2011

I've been alerted to a couple reports that on 2011-03-22, the Russian government decided NOT to allow the Irkutsk Oblast to transition from IRKT (UTC+8) to KRAST (UTC+7+1) on 2011-03-27, and that instead Irkutsk transitioned to IRKST (UTC+8+1) under the existing Russian DST rules and plans to stay there for the time being like the rest of the country. The articles are in Russian, which I don't speak, but I've provided excerpted Google translations below. The reports follow: http://www.irk.ru/news/20110325/time/ (2011-03-25) Irkutsk region remains in its time zone March 27 residents of the Irkutsk region with the rest of the Russians set the clock forward one hour. Previously reported that the Angara will not translate clock to daylight saving time and thereby reduce the difference with Moscow, with 5:00 to 4. Irkutsk officials have prepared all necessary documents. However, an official decision on this has not been signed. In this case, the matter has not withdrawn completely, but only postponed indefinitely. http://gazetavremya.ru/day/16739-irkutskaya-oblast-poteryalas-vo-vremeni.ht… Irkutsk region is lost in time After that we asked for comments to the Legislative Assembly of Irkutsk region Yuri Faleichik, who confirmed this information and added that it is the most painless for our scheme to reduce the time difference with the capital from 5 to 4 hours. And suddenly, on Tuesday revealed that information on the transition to Krasnoyarsk time was premature! The same Jury Faleichik told our newspaper: - The decision to move the Irkutsk region in the time zone of the Krasnoyarsk Territory Government is not accepted. Our source in the regional government said that the decision "not to move to Krasnoyarsk time" was made in connection with the upcoming elections. -- Tim Parenti

Re: Samoa's plans to shift the Inetrnational Dateline
by Gwillim Law April 18, 2011

April 18, 2011

The International Date Line is not defined by any international law or treaty. It is an arbitrary line drawn by cartographers, separating lands in the Pacific Ocean whose standard time is later than UTC from those whose standard time is earlier than UTC. Therefore, if Samoa decides to shift its standard time from UTC-11 to UTC+13, the cartographers will simply redraw the line to the east of Samoa. The same thing happened in 1995, when Kiribati changed the date for its eastern island groups. The Line Islands and the Phoenix Islands had been observing a different date, one day earlier than the Gilbert Islands where most of the people of Kiribati lived. In 1995, the Line and Phoenix groups were shifted forward by one day. They didn't need the approval of any international agency. In response, new maps began appearing with a large displacement in the International Date Line, skirting all of Kiribati along the country's eastern limit. "... the term 'International Date Line' is thus in fact a misnomer. Its exact course was never defined by any international treaty, law or agreement." (http://www.phys.uu.nl/~vgent/idl/idl.htm) "The IDL drawn on the map on this page and all other maps is now and always has been an artificial construct of cartographers-the precise course of the line in international waters is arbitrary. No international organization nor any treaty between nations has fixed the "straight line" segments and their junctions. All nations unilaterally determine their standard time zones..." (http://en.wikipedia.org/wiki/International_Date_Line) I hope that addresses your question adequately. Yours, Gwillim Law ----- Original Message ----- From: Leilani Tuala Warren The Samoa law Reform Commission has been tasked with looking into how Samoa can shift the international dateline so that it is in the same time zone as NZ, Fiji and Tonga rather than USA. Can we please enter into some dialogue as to how this can be done on a global scale?

Compiler Warnings

April 13, 2011

Here are some compiler warnings that it would probably be good to be rid of. The compiler is optimizing away intended overflow tests in some cases. Results of integer operations are officially undefined when overflow occurs, so the compiler is within its rights in making this kind of assumption. $ gcc -Wall -O3 -c *.c localtime.c: In function ‘timesub’: localtime.c:1541: warning: assuming signed overflow does not occur when assuming that (X + c) < X is always false localtime.c:1545: warning: assuming signed overflow does not occur when assuming that (X - c) > X is always false localtime.c: In function ‘T.144’: localtime.c:1727: warning: assuming signed overflow does not occur when assuming that (X + c) < X is always false localtime.c:1738: warning: assuming signed overflow does not occur when assuming that (X + c) < X is always false localtime.c:1748: warning: assuming signed overflow does not occur when assuming that (X + c) < X is always false localtime.c:1752: warning: assuming signed overflow does not occur when assuming that (X - c) > X is always false localtime.c:1768: warning: assuming signed overflow does not occur when assuming that (X - c) > X is always false zdump.c: In function ‘main’: zdump.c:442: warning: assuming signed overflow does not occur when assuming that (X - c) > X is always false $ gcc --version gcc (Ubuntu 4.4.3-4ubuntu5) 4.4.3 -- Andy Heninger

doubled-word typos in timezone/europe and southamerica
by Jim Meyering April 11, 2011

This fixes three instances of doubled words in the "europe" and "southamerica" files. I noticed these in glibc's files, which may well be out of date.

FW: last call for draft-lear-iana-timezone-database-03
by Eliot Lear April 11, 2011

April 11, 2011

Hi everyone, We need your help. We have made substantial progress in seeing to a permanent home for the TZ database and mailing list after Arthur David Olson's retirement. The announcement below indicates that the Internet Engineering Steering Group (IESG) is now asking for feedback on the proposal, which is for the function to be homed by the IANA (Internet Assigned Numbers Authority). The intent, again, is to document existing practice, and to establish a succession process. Now is the time for you to signify your agreement or disagreement with this proposal. Please send your comments to ietf(a)ietf.org, perhaps copying this mailing list. The IESG needs to hear from you as the most impacted community. Please do let them know what you think.

FW: Test cases for zoneinfo data
by Olson, Arthur David (NIH/NCI) [E] April 10, 2011

April 10, 2011

I'm forwarding this message from Christopher Hunt, who is not on the time zone mailing list. Those of you who are on the list, please direct replies appropriately. --ado -----Original Message----- From: Christopher Hunt [mailto:huntc@internode.on.net] Sent: Thursday, December 16, 2010 12:15 To: tz(a)lecserver.nci.nih.gov Subject: Test cases for zoneinfo data Hi there, I'm creating a set of Java classes that closely reflect the structure of the Zoneinfo database. My requirement is driven mostly by wanting to dynamically update Java TimeZone classes i.e. as opposed to compiling a zoneinfo data and re-starting my application. In addition I feel that the ICU and Sun classes do not accurately reflect Zoneinfo structures. I shall open-source this project once it gets to a working point. It'd be terribly helpful if I could get hold of some test cases, automated or otherwise, that verify correct time zone calculations. Would anyone out there have such things? Kind regards, Christopher

My implementation closely honours the domain model of Zoneinfo. My project can be found at: http://zoneinfo-tz.codehaus.org/ I was wondering if the Zoneinfo website could be updated to include a link to it under the "Other tz- based time zone software" heading, and possibly just underneath the Sun Java line. Thanks for the consideration! Kind regards, Christopher

Re: www.twinsun.com down
by Christopher Hunt April 10, 2011

April 10, 2011

Hi there, Any further advice on this? I noticed it was down too and, while it doesn't effect the ftp site, it is a little disconcerting. After all, zoneinfo is incredibly important! Going forward, do you see that there could be a more appropriate place for the zoneinfo website and its corresponding ftp site to live (even if it is just from a DNS perspective)? Kind regards, Christopher
