What about Western Sahara time ?
by Alex Krivenyshev May 9, 2008

May 9, 2008

Is Western Sahara (part which administrated by Morocco) going to follow Morocco DST changes ? Any information? What about other part of Western Sahara - under administration of POLISARIO Front (also named SADR Saharawi Arab Democratic Republic) ? Alex Krivenyshev, http://www.WTZ.com New York, NY

UTC offset for Asia/Choibalsan
by Deborah Goldsmith May 4, 2008

May 4, 2008

We received a bug report claiming that the tz database UTC offset for Asia/Choibalsan (GMT+09:00) is incorrect, and that it should be GMT +08:00 instead. Different sources appear to disagree with the tz database on this, e.g.: http://www.timeanddate.com/worldclock/city.html?n=1026 http://www.worldtimeserver.com/current_time_in_MN.aspx both say GMT+08:00. Do we have any independent confirmation of the correct offset for Asia/ Choibalsan? Thanks, Deborah Goldsmith Apple Inc. goldsmit(a)apple.com

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

FW: Setting time zone in c language

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.
