Re: Samoa's plans to shift the Inetrnational Dateline
by Gwillim Law April 19, 2011

April 19, 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.

Update for Russia?

Hi, I was wondering if there is any timeline for an update to address the changes in Russia? My understanding is we were blocked on knowing what name will be used after the change. Is that still the case? Thanks, Deborah

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)?

Compiler Warnings
by Andy Heninger April 13, 2011

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

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

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
