RE: Nunavut (northern Canada) changes time zones again
by Jesper Nørgaard Nov. 30, 2000

Nov. 30, 2000

There was news about the Nunavut time zones in Nuniatsaq News the 10.th. of November, but I didn't see it until today. The link is http://www.nunatsiag.com/archives/nunavut001130/nvt21110_02.html although this seems to be a dynamic address with date and time; Check out the Nunatsiaq News archives from 10.th of November to find the article, if the above doesn't work. Quote: "After a week of confusion, clocks in the territory's westernmost hamlets are now synchronized - an hour behind the rest of Nunavut. The Nunavut government last week retreated from its unified-time-zone policy, permitting Kugluktuk and Cambridge Bay to stay on central time for the winter. ... Anawak said the Nunavut government would allow its employees in Kugluktuk and Cambridge Bay to operate on central time year-round, putting them one hour behind the rest of Nunavut for six months during the winter." The only way I can get this to match, is if Kugluktuk and Cambridge Bay will be on Central Time all year round (e.g. GMT-6 with DST) while the rest of the central and eastern Nunavut will be on Eastern Standard Time all year round (e.g. GMT-5 without DST), so that during winter Kugluktuk will be one hour behind, and in the summer will be on the same time as the rest of Nunavut. This implicitly means that Central and Eastern Nunavut does *not* have daylight saving. I wonder if any of you have any comments on this, or more official documentation. The above article seems to go to great lengths to express daylight saving issues without mentioning the (forbidden?) term "daylight saving". Perhaps it has become too political in Nunavut to imply that you can gain something with "daylight saving" ;) ? Can the article be interpreted any other way?

Re-entrant, any-zone mktime()-equivalent?
by Jonathan Lennox Nov. 17, 2000

Nov. 17, 2000

Has anyone ever developed patches for tzcode to support a function that is the equivalent of timelocal()/mktime() and timegm() for arbitrary time zones? What I'm looking for is something that would be the rough equivalent of: time_t timetz(struct tm *tm, char *tz) { time_t t; char *oldTZ = getenv("TZ"); setenv("TZ", tz, 1); tzset(); t = mktime(tm); if (oldTZ != NULL) { setenv("TZ", oldTZ, 1); } else { unsetenv("TZ"); } tzset(); return t; } However, I'd like to have a function which a) worked correctly in multi-threaded environments, and b) reported an error message if the timezone string was invalid, rather than just falling back to GMT. I need this for a Internet Telephony server which needs to support time-of-day routing for users in arbitrary timezones, and I want to use the TZ database names to identify these timezones. (This is for an implementation of the Call Processing Language, soon (pending IESG approval) to be an IETF Proposed Standard. <http://www.cs.columbia.edu/~lennox/draft-ietf-iptel-cpl-04.txt>.) Obviously, writing such a function would require some fairly intrusive hacking on tzcode -- especially since tzcode uses static variables rather liberally. Before I start bashing on the code, I'd appreciate any advice anyone else has, especially if the work's already been done. Thanks for any advice or pointers anyone can give! -- Jonathan Lennox lennox(a)cs.columbia.edu

Brazil: Fernando de Noronha
by Oscar van Vlijmen Nov. 7, 2000

Nov. 7, 2000

I have checked this against the large Times atlas and my grammar Portuguese. The atlas says Fernando de Noronha. The preposition 'de' means just: from, of. 'Do' however is a contraction of the preposition 'de' and the article 'o'. I believe it's therefore correct to say Rio Grande do Norte (in the North) and Mato Grosso do Sul (in the South), but Fernando de Noronha (from Noronha). Regards, Oscar van Vlijmen 2000-11-07

RE: LHI daylight savings (fwd)
by Jesper Nørgaard Nov. 4, 2000

Nov. 4, 2000

James Lonergan's confirmation that LHI always advanced clocks going into DST at 2:00 local time, refutes the idea that Sydney and LHI has always been in sync, apart from the half hour difference while not in DST. I guess I overinterpreted James Lonergan, and apologize for that. I should have asked him instead (I thought I did, but couldn't find the mail, so I probably didn't). I agree that the patch should be rolled back. We should document history in the time zone area, not invent it :) Seen in retrospect, this was probably not a very good guess either. Only EEC (the western part of Europe) has notably made a system where all the countries are going in and out of DST the exact same second (in GMT) while not even USA is doing that, much less Canada, Russia or even Australia (from which Lord Howe Island belongs).

week starts at Sunday or Monday??
by Christoph Bugel Nov. 2, 2000

Nov. 2, 2000

I've written a nice Date Time class library to get a grip on Daylight Saving Time bugs. It is mostly a wrapper around the existing stuff from #include <time.h>, but the idea is to force the user to forget about those, and be forced to think what timezone he is talking about. (I have a class TZone, which user MUST supply if he want to construct a date, or if he want to break it down into readable fields). and also the idea is to make clear what the isdst flag semantics are, etc. I am putting the finishing touches, and I now decide on a few trivial questions (which seem inportant anyhoow..) (1) I decided to have the MONTH and the WeekDay 1-based (in struct tm they start at zero). I guess there are arguments for both, but I didn't like the inconsistency between weekday (0-6) and monthday (1-31). also, if month is (0-11) I have to add 1 before printing, because users are definitely used to december as month 12, not month 11. so my question is.... now that I decided that days are niumbere 1 to 7, what is day 1 ??? is it Sunday, or Monday? what is the Right Thing to do? regards, Christoph

I forgot one entry in my last mail: Manoel Andrade <mandrade(a)hotlink.com.br> reported to me that some states/territories in Brazil have stopped using DST, just about a week after the DST period started. Now looking at the official page http://pcdsh01.on.br/DecHV.html : It seems that Pernambuco and Roraima stopped using DST on 15 October at midnight. Then, just one week later, Sergipe, Alagoas, Paraiba, Rio Grande do Norte, Ceará, Piauí and Maranhão stopped using DST on 22 October at midnight.

Re: LHI daylight savings (fwd)
by David Keegel Oct. 24, 2000

Oct. 24, 2000

I wrote to James Lonergan to clarify the situation about what time DST starts on Lord Howe Island exactly. ----- Forwarded message from James Lonergan ----- From: "James Lonergan" <kingfish(a)bigpond.com> To: "David Keegel" <djk(a)cyber.com.au> Subject: Re: LHI daylight savings My apologies for not responding earlier...I have been on leave. Lord Howe Island advances clocks by 30 minutes during DST in NSW and retards clocks by 30 minutes when DST finishes. Since DST was most recently introduced in NSW, the "changeover" time on the Island has been 02:00 as shown on clocks on LHI. I guess this means that for 30 minutes at the start of DST, LHI is actually 1 hour ahead of the rest of NSW.

RE: ISO 8601 assumption
by Jesper Nørgaard Oct. 18, 2000

Oct. 18, 2000

I even disagree about the assumption that yyyy-mm-dd is unambigous, because if the month number and the day-in-month number can be confused, they surely will according to Murphy's law, e.g. some people will create yyyy-dd-mm dates just as surely as they will create mm-dd-yyyy dates. I have always liked another standard, the yyyy-mmm-dd standard, because no matter how you interchange the elements, they are always unambigous, e.g. 08-OCT-2000, AUG-10-2000 or even 2000-01-JAN can't be misinterpreted simply because each element has different length. Unfortunately this standard has not gained much recognition, perhaps because it assumes english as the base language for the acronyms (JAN, FEB, MAR ...). That humanity has still not come up with a completely unambigous date format which is generally accepted, really shows how much IT is still in it's infancy. From a technical point of view it is a trivial problem, but of course it should be human-readable. Another similar problem is the myriad of ambigous ways that we identify a computer user, without really getting certain WHO it is. I am talking about those 40+ different account names with corresponding password I'm keeping in a password keeper program, about all the different finger print, eye scanner systems etc. that have been developed isolated, still without reaching a simple way to identify a computer user. Maybe in 20 years I will laugh of this mail because the solution has been implemented everywhere, but at the moment I think it is a big problem that is the real reason why e-commerce is still not raving off with millions of computer based transacions. Who are you giving credit? The 5-year old son of a well-known user? You'll have to guess. Meanwhile, why yyyy-mmm-dd or some other completely unambigous date format could not become international standard is beyond me. We *could* begin by defining an unambigous standard for the tzdata list though. I realize of course that isolated seen tzdata is already unambigous because it is already stated *somewhere* which standard has been used. My apologies for drifting a bit away from the original issue.

No, no such assumption can be made. Using hyphens to separate elements in a date was well-established practice in the United States before there ever was an ISO. The only time you can assume that a date is written in ISO 8601 format is when the full yyyy-mm-dd form is used. -GAWollman

ISO 8601:1988 available in PDF form
by Peter Ilieve Oct. 16, 2000

Oct. 16, 2000

Last Friday Sun made the source code for Star Office available from http://www.openoffice.org. What has this got to do with the timezone list you might ask. Well, one of the projects is to produce an XML based file format for use by Open Office (http://xml.openoffice.org) The Related Documentation section of the draft spec (http://xml.openoffice.org/xml_spec_draft.pdf) gives a URL for ISO 8601: http://www.iso.ch/markete/8601.pdf. Sure enough, the PDF file is there, available for anyone to download for free. (I hadn't seen this mentioned here before, but a quick check of Markus Kuhn's date and time page at http://www.cl.cam.ac.uk/~mgk25/iso-time.html shows that he has a link to this PDF file so he has obviously already spotted this.)
