file-format
by hsv＠tbbs.net Oct. 27, 2008

Oct. 27, 2008

The man-page describes a fairly loose fileformat, but the actual files show less loosness: there is no quoted sharp (#), all one name s Rules are in a bunch in time order, with no other Rule or Zone in between, all weekday-names are three-letter-long abbreviations of capital letter and twain small letters. Can I afford to count on that, or is it really needful to pars a much looser-formatted file than really is there?

Makefile cleanup to make distro' lives easier
by Mike Frysinger Oct. 26, 2008

Oct. 26, 2008

what are the target systems for tzcode ? how do people feel about cleaning up the Makefile to better fit up-to-date systems ? we're carrying a Makefile clean up patch in Gentoo here: http://sources.gentoo.org/sys-libs/timezone-data/files/timezone-data-2008h-… and really, most of that is generic ... -mike

Looking for advices regarding tzdata
by Dmitri Pal Oct. 24, 2008

Oct. 24, 2008

Hi, I am new to tzdata and advanced time zone conversion technics that it offers. I read couple articles about tzdata on wikipedia and in man pages. So far I do not see what I am looking for so may be it just does not exist. Here is what I am trying to accomplish. Input: YYYYMMDDHHMMSS - date or some other date format that can be easily broken into tm structure. TZ information - I was hoping to use some kind of meaningful string so time zone names. Names from zone.dat would work perfectly. Output: Number of seconds since 1 Jan 1970 in UTC time that corresponds to the time stamp Processing: * The function that would do the conversion needs to parse and validate the format before conversion can happen. That includes validating the TZ name. * Would be nice to use standard libc functions to do this conversion as much as possible What is missing: I am currently on Red Hat Enterprise Linux 5.1. It has /usr/share/zoneinfo and there I found zone.dat. Is there any function or set of functions that allow me to interact with this database like: get_next_timezone_name - to iterate through the list and get the timezone. Is there any abstraction around this file? In different distributions it can be in different places and under different names. But libc functions hide this complexity so is there any API that will let me to enumerate timezones and or check if the XXXX/YYYY is the correct valid time zone name without dealing with the file myself? Also the other part is determining the daylight savings at the moment of conversion in the specified time zone? Would it be something like breaking the input I have into the tm structure , calling tzset(timezonename) and then call mktime? #include <time.h> #include <stdlib.h> time_t my_time (struct tm *tm, char *timezonename) { time_t ret; char *tz; tz = getenv("TZ"); setenv("TZ", timezonename, 1); tzset(); ret = mktime(tm); if (tz) setenv("TZ", tz, 1); else unsetenv("TZ"); tzset(); return ret; } This example is based on the timegm example but seems to contradict mktime man page that states that mktime sets the timezone variable itself. In other words I can populate a part of the tm from the data I have but I need to populate the tm_isdst based on the timezone. Would the code above accomplish the task? I feel like something might be wrong with this but I am not sure what. So this is where I am and I am bit lost. Please advise. Thank you Dmitri Pal

proposed time zone data changes for Argentina
by Arthur David Olson Oct. 23, 2008

Oct. 23, 2008

Here are proposed changes to southamerica and zone.tab to reflect changes in DST handling in Argentina. These are based on Mariano Absatz's patch; I've added a credit for Mariano, anchored the URLs, and preserved the ordering of zones in the southamerica file (to minimize differences with the current version). (In the future, we may want to revisit Argentina to remove now-superfluous comments and reorder the zones.) If no one finds problems, these changes will show up in the ftp versions on 2008-10-27. --ado diff -r -c old/southamerica new/southamerica *** old/southamerica Wed Oct 8 08:46:17 2008 --- new/southamerica Mon Oct 20 12:57:20 2008 *************** *** 1,4 **** !

Olson Timezone Database does not have Australian daylight timezones
by Burns, Jamie BGI SYD Oct. 22, 2008

Oct. 22, 2008

Hi. I have 2 change requests for the Olson Timezone Database I noticed today that the Olson Timezone Database has incorrect timezones Australia. I noticed this in an application running on Sun's Java VM. Sun's Java VM uses the Olson Timezone Database as its timezone reference. The application returned the correct time but appended the incorrect timezone. The application returned "22 Oct 2008 at 15:54 EST" The application should have returned "22 Oct 2008 at 15:54 AEDT" Could the Australian timezones in the Olson Timezone Database be corrected to report daylight timezones during periods of daylight savings. Further to this, the Australian timezone names in the Olson Timezone Database are not at all consistent with the timezone names published by the Australian government. The Australian government has a complete list of Australian timezones at http://www.australia.gov.au/Time. Could the Australian timezones in the Olson Timezone Database be updated to the timezones published by the Australian government. Thanks.

symlinking /etc/localtime in zic.c
by Mariano Absatz - El Baby Oct. 21, 2008

Oct. 21, 2008

Hi, I recently used 'zic -l' on a machine where /usr is on a different filesystem than /etc and I saw the lines where this happens (in the dolink() function). Up until some time, I didn't know about "-l" and used to create a symlink from /usr/share/zoneinfo/What/Ever to /etc/localtime At that time, I was about to ask if it wouldn't be better to create a symlink rather than a copy, but then I found out that linux distros prefer to make a copy rather than a symlink because /usr might not be mounted during boot and /etc/localtime would be pointing to no file... http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=346342 http://www.redhat.com/archives/rhl-devel-list/2006-April/msg00019.html Now... IF the first result = link(fromname, toname); fails, it is quite probably an indication that /usr is on a different filesystem than / ... woulnd't it be better in that case to copy rather than symlink it?
