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).

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.

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

Brazil again
by Steffen Thorsen Oct. 31, 2000

Oct. 31, 2000

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.

If you are interested then take a look at www.timemap.f2s.com, the site is still under construction but it has a few screenshots and descriptions of the program. The program itself is still in the beta stage, however this should change hopefully in the next week or so. If you are interested in beta testing, please give me an email. I will allow for a few testers however I would expect useful comments and criticisms in exchange for the free software. That's about it... oh and if anyone knows anything about Kazakhstan Time Zones or knows of any place where I can find any information about them then please email me. Thanks! Marek O.

Quick start for new member
by Floriano Oct. 30, 2000

Oct. 30, 2000

Dear Friends, PLEASE! As a new member of this listing, I think it's a little bit hard to understand how to use the TZ database, I tried to read all files, but I don't get the right information. Somebody could tell me about: 1. Is there some readme files explaining how to use the tz code and database? 2. Is there some demo program or tutorial about TZ ? 3. Is there another sites about the TZ database? PLEASE! I really need to understand TZ. I know C language very well. I just couldn't figure out how to use TZ. I would like to build a program that shows by country the TZ and DLS info. Somebody pick a country and some date, and the program will say if that time was in DLS and what TZ was that time. Thanks in advance! Floriano Caldeira floriano(a)ilhanet.com.br
