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

FW: Setting time zone in c language
by Olson, Arthur David (NIH/NCI) [E] April 16, 2008

I'm (belatedly) forwarding this message from vinod L R, who is not on the time zone mailing list. Those of you who are on the time zone mailing list, please direct replies appropriately. --ado From: Vinod L R [mailto:vinodl@aztecsoft.com] Sent: Tuesday, April 08, 2008 1:25 To: tz(a)lecserver.nci.nih.gov Subject: Setting time zone in c language Hi, I have a GUI interface ,where in user selects the Area (for ex: Africa) and Zone name(for ex: Cairo).How do i map this /etc/TZ file,as there will be different Area and Zone to be set.Is there any functions in "C' which would solve my issue or any other method ? I found that uClibc uses /etc/TZ to set the time zone it does not use /etc/localtime nor does it understand the timezone data .so will changing UCLIBC_TZ_FILE_PATH it to /etc/localtime in uClibc-0.9.29.config file will solve my issue?? how do I map this to /etc/localtime so as to set a valid timezone. The procedure I tried is : ln -sf /usr/share/zoneinfo/Africa/Cairo /etc/localtime. alternatively I find that executing echo CET-1DST >/etc/TZ does work.

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". Is it a problem or actually what I am thinking is wrong? Thanks, Michael Shao System Support Eng./Tech. Engineering Support.
