No backward zone name entries in zone.tab
by Herton Ronaldo Krzesinski May 2, 2008

May 2, 2008

Hi, Currently it seems timezone in general has a problem related to backward zone names and entries in zone.tab. Every time the name of a zone changes, its entry is replaced in zone.tab file and added to backward file as a Link, until now no problem, but after you install timezone how you can get the zone.tab entry when using the old zone name? Is there a way to do this, or shouldn't both the new and old zone name stay in zone.tab? For now I made this set of commands to add back zone names to zone.tab based on backward file: chmod +w zone.tab echo -e "\n# zone info for backward zone names" >> zone.tab cat backward | grep Link | while read link curr old; do if [ -z "$curr" -o -z "$old" ]; then echo "Error processing backward entry for zone.tab" exit 1 fi cat zone.tab | grep -v '^#' | grep "$curr" | \ while read l; do if [ "`echo \"$l\" | awk 'BEGIN { FS = \"[\t]\" } \ { print $3 }'`" = "$curr" ]; then echo "$l" | sed "s|$curr|$old|" >> zone.tab \ || echo ERROR >> zone.tab else echo ERROR >> zone.tab fi done done if grep -q "^ERROR" zone.tab; then echo "Error adding backward entries to zone.tab" exit 1 fi Without old zone names in zone.tab, problems like this can happen when applications still use old zone names: https://qa.mandriva.com/show_bug.cgi?id=40184 Other solution would be to just install backward file in the system to allow applications to know the zone that changed names and use the new name. -- []'s Herton

Daylist savings letter modifiers for zone format in Australia
by Mark Rodrigues May 2, 2008

May 2, 2008

Hi, This is my first post in this mailing list so please redirect me to an etiquette page if I do anything wrong :) I am using the tzdata2008b.tar.gz distribution from the 24/03/2008. Using the Australia/Melbourne zone, it seems to imply that the format of the zone is EST regardless whether I am in day light savings or not. According to this article [http://www.australia.gov.au/Time_Zones] the format should be AEST except during daylight savings in which case it is AEDT. It also indicates that there may be problems with all the zones in the Australian region. So a couple of questions: 1. What is the best way for me / us to verify this is right? Is that fact that it is on a government web-site enough? 2. If this is correct what is the best way to update the data file. I am more than happy to change it and send back for review and incorporation if required / appropriate. If you need any more from me please let me know. Thanks and kind regards Mark Rodrigues http://www.codeplex.com/zoneinfo

Proposed changes for Argentina, tzfile.5, and strerror
by Arthur David Olson March 31, 2008

March 31, 2008

Here are proposed changes to the time zone package: 1. Most importantly, changes to the "southamerica" file (combinining material from Jesper Norgaard Welen and Paul Eggert) to reflect Argentina's readoption of daylight saving time. 2. Jonathan Leffler's fixes to tzfile.5. 3. Changes to eliminate HAVE_STRERROR and the conditional strerror definition. (A safe change since it should have no run-time effects; we'll see if anybody complains about uncompilability). Barring problems these changes are to show up on the ftp site on Monday morning as usual, just in time to be late for the Argentina party. --ado ------- southamerica ------- *** /tmp/geta2179 Thu Dec 27 12:24:03 2007 --- /tmp/getb2179 Thu Dec 27 12:24:03 2007 *************** *** 1,4 **** ! # @(#)southamerica 8.13 # <pre> # This data is by no means authoritative; if you think you know better, --- 1,4 ---- ! # @(#)southamerica 8.14 # <pre> # This data is by no means authoritative; if you think you know better, *************** *** 106,111 **** --- 106,123 ---- # from the International Date Line.

Expected output of zdump(8)
by Edwin Groothuis March 28, 2008

March 28, 2008

Greetings, I was wondering why zdump(8) was so slow on one of my machines. It's a known issue, old zdump.c code. So I grabbed a copy of the new zdump.c from tzcode2008a. But it raised a couple of questions for me. On a 32 bit machine running FreeBSD 6.3 I get this: (/etc/localtime is /usr/share/zoneinfo/Australia/Sydney) [~/tzcode] edwin@k7>./zdump -v /etc/localtime /etc/localtime Fri Dec 13 20:45:52 1901 UTC = Sat Dec 14 06:45:52 1901 EST isdst=0 /etc/localtime Sat Dec 14 20:45:52 1901 UTC = Sun Dec 15 06:45:52 1901 EST isdst=0 /etc/localtime Sun Dec 31 14:00:59 1916 UTC = Mon Jan 1 00:00:59 1917 EST isdst=0 /etc/localtime Sun Dec 31 14:01:00 1916 UTC = Mon Jan 1 01:01:00 1917 EST isdst=1 [...] /etc/localtime Sat Oct 3 15:59:59 2037 UTC = Sun Oct 4 01:59:59 2037 EST isdst=0 /etc/localtime Sat Oct 3 16:00:00 2037 UTC = Sun Oct 4 03:00:00 2037 EST isdst=1 /etc/localtime Mon Jan 18 03:14:07 2038 UTC = Mon Jan 18 14:14:07 2038 EST isdst=1 /etc/localtime Tue Jan 19 03:14:07 2038 UTC = Tue Jan 19 14:14:07 2038 EST isdst=1 On a 64 bit machine running FreeBSD 6.3 I get this: [~/tzcode] edwin(a)mavetju.org>./zdump -v /etc/localtime /etc/localtime -9223372036854775808 = NULL /etc/localtime -9223372036854689408 = NULL /etc/localtime Sun Dec 31 14:00:59 1916 UTC = Mon Jan 1 00:00:59 1917 EST isdst=0 gmtoff=36000 /etc/localtime Sun Dec 31 14:01:00 1916 UTC = Mon Jan 1 01:01:00 1917 EST isdst=1 gmtoff=39600 [...] /etc/localtime Sat Oct 3 15:59:59 2037 UTC = Sun Oct 4 01:59:59 2037 EST isdst=0 gmtoff=36000 /etc/localtime Sat Oct 3 16:00:00 2037 UTC = Sun Oct 4 03:00:00 2037 EST isdst=1 gmtoff=39600 /etc/localtime 9223372036854689407 = NULL /etc/localtime 9223372036854775807 = NULL That big positive and negative number is the effect of gmtime(). I got the same results on the 64 bit version of Linux FC6. Now my question is... Is this behaviour "as expected" and the same on other 64 bit operating systems like Solaris, MacOS/X and others (if you have one name it :-) ?

About australia/melbourne time zone
by Shao, Michael March 27, 2008

March 27, 2008

Hi, I downloaded the latest version of timezone package and applied it on Linux machine. when I use "zdump -v" command to show Melbourne zoneinfo, I got first two lines shown as below: Australia/Melbourne Sat Apr 5 15:59:59 2008 UTC = Sun Apr 6 02:59:59 2008 EST isdst=1 gmtoff=39600 Australia/Melbourne Sat Apr 5 16:00:00 2008 UTC = Sun Apr 6 02:00:00 2008 EST isdst=0 gmtoff=36000 In my opinion, in the first line, the word "EST" (which I marked with red colour)should be "'EDT".

Iran uses DST again
by Hedayat Vatnakhah March 27, 2008

March 27, 2008

Hi all, From 2008, Iran uses DST again which was not used for some years. In Jalali calendar, it starts on 1/1 and it'll end on 06/30. In Gregorian calendar, it starts on 03/21 and ends on 09/21. But every 4 years (2008 is one of them) on our leap years, it'll become 03/20 and 09/20. I was unable to find any English reference, but anyway, the following references mention this change. The latter contains the exact text of the law: http://fa.wikipedia.org/wiki/%D8%AA%D8%BA%DB%8C%DB%8C%D8%B1_%D8%B3%D8%A7%D8… http://www.rooznamehrasmi.ir/Detail.asp?CurPage=2&NewsID=993144394738441 Thanks, Hedayat

The file... ftp://elsie.nci.nih.gov/pub/tzdata2008b.tar.gz ...is now available; this reflects the changes circulated last week on the time zone mailing list (including renaming Asia/Calcutta to Asia/Kolkata, with a backward link provided). It's the season for changes, and I'm still hoping to get good documentation on what happened in Venezuela earlier this year, so expect a tzdata2008c.tar.gz fairly soon. --ado

In https://launchpad.net/bugs/121540, Vientamese users make quite a clear statement that "Saigon" is obsolete and, more importantly, politically sensitive. The current name of that city has been "Ho Chi Minh" for very long, so it should be renamed to "TP Ho Chi Minh", and Saigon should get a transitional link. Last time it was already proposed to use the capital "Hanoi" instead or in addition, but I understand that you usually use the largest city, not capitals. I take it that didn't change?

Re: Possible error with timezone for Saint Pierre/Miquelon?
by Hancock, David (dhancock) March 17, 2008

March 17, 2008

We have fixed this by hand-entering the timezone name as "America/Miquelon." The web server we used to obtain the timezone (given lat/lon coordinates) gave "Etc/GMT-3" and that was the primary source of our confusion.

Renaming Saigon to TP Ho Chi Minh
by Martin Pitt March 17, 2008

March 17, 2008

Hello tzdata developers, I already contacted you about this a little while ago, but the discussion didn't get very far. In https://launchpad.net/bugs/121540, Vientamese users make quite a clear statement that "Saigon" is obsolete and, more importantly, politically sensitive. The current name of that city has been "Ho Chi Minh" for very long, so it should be renamed to "TP Ho Chi Minh", and Saigon should get a transitional link. Last time it was already proposed to use the capital "Hanoi" instead or in addition, but I understand that you usually use the largest city, not capitals. I take it that didn't change? Thanks for considering, Martin -- Martin Pitt | http://www.piware.de Ubuntu Developer (www.ubuntu.com) | Debian Developer (www.debian.org)
