tzcode and autoconf ?
by phdemuyt＠ulb.ac.be Sept. 25, 1996

Sept. 25, 1996

I have just downloaded tzcode96l.tar.gz, and tried to compile it on sysv68 R3V7.1 (Motorola MVME167 board with 68040 processor), and it failed with the following : cc -DTZDIR=\"/usr/local/etc/zoneinfo\" -c zic.c **Error: ./private.h: 72: Can't find include file stdlib.h **Error: zic.c: 9: Can't find include file locale.h *** Error code 1 Stop. I can solve that myself, but, looking in the sources, I have seen many autoconf-like HAVE_<something> symbols. I like the ability provided by autoconf to automatically deduce system characteristics, and to compile in a separate directory. Is there an autoconf'ed version of tzcode somewhere ? On a related point : the copyright for this code is public-domain. Would it not be better protected by the GPL ? Regards Philippe De Muyter

Re: how to install new tz data on BSD/OS ?
by Gildas Perrot Sept. 20, 1996

Sept. 20, 1996

Hi, BSD/OS 2.1 uses the new zoneinfo but not BSD/OS 1.1. I have one last BSD/OS 1.1 system and I have problems to change its zoneinfo. I got the sources of code and data of tz in ftp://elsie.nci.nih.gov/pub/. 1) zic europe gives : "europe", line ...: input line of unknown type It seems that zic which comes with 1.1 is not compatible with new source format. 2) I got zoneinfo sources and I compiled zic with 'make zic'. First, I had to remove yearistype in zip entry in Makefile since yearistype.sh doesn't appear in sources. I got a new zip which could compile the tz data. I did "zip europe" and "zip -l Europe/Paris" but /etc/localtime stays the same. I copy Europe/Paris to /etc/localtime and this time, the perl script "http://wsspinfo.cern.ch/file/find_dst.pl" says : Today is Fri Sep 20 13:12:31 1996, DST is off The current value of TZ is <not set> No DST change in the next 20 weeks instead of : Today is Fri Sep 20 15:12:7 1996, DST is on The current value of TZ is <not set> The next DST change will be Sun Sep 29 2:59:59 1996 one second later it will be Sun Sep 29 2:0:0 1996 as before the installation of the new /etc/localtime. Any idea about the problem ? Thanks in advance for your help. Gildas. -- Gildas PERROT, perrot(a)francenet.fr __o FranceNet, 28 rue Desaix, 75015 Paris ---_ \<,_ ---- (_)/ (_)

how to install new tz data on BSD/OS ?
by Gildas Perrot Sept. 19, 1996

Sept. 19, 1996

Hi, I am using BSD/OS systems which use tz data as BSDI support seems to say. I would like to know how to install tz data to incorporate new european summertimes (I am in MET-1METDST) as HP said : All countries member of the European Community should implement the new summertime guidelines for 1996/1997. From now on in all these countries the switch from wintertime to summertime will be done on the same day (switching back also). The changes are : # Mitteleuropaeische Zeit, Mitteleuropaeische Sommerzeit MEZ-1MESZ 0 3 25-31 3 1983-2038 0 MESZ-2 0 2 24-30 9 1983-1995 0 MEZ-1 0 2 25-31 10 1996-2038 0 MEZ-1 # Middle European Time, Middle European Time Daylight Savings Time MET-1METDST 0 3 25-31 3 1983-2038 0 METDST-2 0 2 24-30 9 1983-1995 0 MET-1 0 2 25-31 10 1996-2038 0 MET-1 # Greenwich Mean Time, British Summer Time GMT0BST 0 3 25-31 3 1983-1984 0 BST-1 0 3 23-29 3 1985-1990 0 BST-1 0 3 25-31 3 1991-1995 0 BST-1 0 2 25-31 3 1996-2038 0 BST-1 0 1 25-31 10 1983-1985 0 GMT0 0 1 23-29 10 1986-1994 0 GMT0 0 1 18-24 10 1995 0 GMT0 0 1 25-31 10 1996-2038 0 GMT0 # Western European Time, Western European Time Daylight Savings Time WET0WETDST 0 3 25-31 3 1983-1984 0 WETDST-1 0 3 23-29 3 1985-1995 0 WETDST-1 0 2 25-31 3 1996-2038 0 WETDST-1 0 1 25-31 10 1983-1985 0 WET0 0 1 23-29 10 1986-1995 0 WET0 0 1 25-31 10 1996-2038 0 WET0 I found that on my systems, I have a crypted /etc/localtime and /usr/share/zoneinfo/ directory with subdir containing TZ info for towns in crypted text.

Well, the official schedule is still to have a Directive agreed by the Council of Ministers by 1 Jan 97. I doubt that this will happen as all previous ones I know of have been late. I reported the Commissions proposals here in May. They were another 4 years of the current rules: year start end 1998 29 Mar 25 Oct 1999 28 Mar 31 Oct 2000 26 Mar 29 Oct 2001 25 Mar 28 Oct If the French are now going to take a few months or so to decide what they want it virtually guarantees that the 8th directive will be late.

Some thoughts ...
by Chris Carrier Sept. 7, 1996

Sept. 7, 1996

Some thoughts ... Markus G. Kuhn <kuhn(a)cs.purdue.edu> suggested that we get more formal, call ourselves the "Timezone Information Center" and let ourselves become more well known. I don't want to requote his entire post but I do favor all his suggestions. Peter Ilieve reported in a message received here on 1996-Sep-05 08:00 GMT: >The BBC Radio 4 news reported this morning that the French prime >minister Alain Juppe has issued some sort of letter indicating that >France will abandon summer time and keep the clocks the same for >the whole year... >The report said a parliamentary commission would now be set up to >decide if France should use GMT+1 or GMT+2 as its standard time. A thought; this October will be the first October that France will be voluntarily on GMT+2. It was involuntarily on GMT+2 during a couple of Octobers during the Nazi occupation. On the last day of GMT+2 this year, sunrise in Paris will be at 8:27, and at Cherbourg, 8:44. If GMT+2 were to become used all year sunrise in Paris would be delayed until 9:44, and in Cherbourg, 10:04! >I didn't catch what it said about the start date for any of this. To which Antoine Leca commented (1996-09-05) :Addition reflexion from myself: this is only a mission; given the prior :art and the time needed for the mission to investigate, I don't expect :this to change the DST rules in France for 1997, and I understand the :goal is the 8th directive. [starting 1998] :BTW, there will be elections in March 1998 in France. >So much for EC Directives. Actually the EC seems to give member states quite a bit of latitude in summer time dates; prior to 1995, the Directives specifically allowed the UK and Ireland authority to end summer time in late October, and that there was once a proposal to synchronize the end of summer time in 1984-6 at the second Sunday in October throughout the EC, but this fell through (source: some errors in the Nautical Almanac). What the EU might consider would be the adoption of something similar to the Uniform Time Act in the United States; set the dates for summer time but allow member states to opt out of the summer time provision if they so choose. Has anyone heard anything about the release date of the 8th Directive?

Suggestion: Timezone Information Center
by kuhn＠cs.purdue.edu Sept. 5, 1996

Sept. 5, 1996

As far as I know, this mailing list represents the best collection of people knowledgeable about time zones and summer time regulations all over the world. There would be many advantages if we could present ourself as a more formal entity to the governments of this world. We could establish something called for instance a "International Timezone Information Center". We could send letters directly or over UN channels to the governments. In these letters, we could invite the government employees responsible for the various national time zones to join our mailing list and we could ask the governments to inform us about any future time zone changes as early as possible. We could also provide for governments information material about the summer time switching algorithms that are currently in use. Such a periodic mailing could be easily created automatically from the most recent tz database. Such a publication would have several effects: - Governments have a chance to check the Olson database contents periodicly (both algorithms and terminology) - Governments are reminded periodicly to inform us whenever they plan to change their time zones - We would get in better contact with other organizations that collect timezone information (CIA, phone companies, etc.) - Governments are made a little bit more aware about the headaches that frequent arbitrary time zone changes and incompatible summer time switching rules can cause in the technical world - We would not have to rely completely on unprecise media reports about planned timezone changes but would get access to more official reports - Governments would get well-engineered examples of how a summer time switching rule should be specified correctly - Governments could perhaps be persuaded to accept a unique ID for their national time zones (I have already seen some good proposals here) All we need is someone who would be willing to operate such a "International Timezone Information Center (ITIC?)", preferably someone working for a big organization or company that is very interested in keeping information about time zones up to date. Perhaps several such organizations (AT&T, Sun, Microsoft, etc.) would be willing to support a time zone information center. The Information Center should under no circumstances be financed by selling the resulting publications. The data should be freely usable, in order to avoid the silly situation that we have with ISO standards (not online and so expensive that almost nobody ever sees a copy them). May be, we could later give this operation a more official touch by writing an ISO standard or an ITU-R TF-series recommendation <URL:http://www.itu.ch/itudoc/itu-r/rec/tf.html> that describes the role of the ITIC (ugly acronym, better suggestions?). We could also establish some more or less formal relations with the UN and the BIH/IERS (Bureau International d'Heure/International Earth Rotation Service, the folks that define UTC as defined by ITU-R).

Chris Carrier says: > It was postulated that Japan would go on DST in 1996, probably using the > American rules of 1st Sunday in April to last Sunday in October.

I have been living in Japan for a year and can confirm that there was no DST this year. Also, although I can't read Japanese newspapers, it's worth pointing out that there was absolutely no mention of the possibility of implementing DST in any English-language periodicals here, as far as I know. The only place I've heard anything about the possibility is on this mailing list. (Of course, this being Japan, perhaps such things are not discussed before they are announced :-)) Stephen Eubank eubank(a)itl.atr.co.jp
