Bug in Argentina timezone
by Ricardo I. Vieitez Nov. 7, 2008

Nov. 7, 2008

There is a bug in the Argentine timezone, as not the whole country but parts of it are GTM-2 because of summer time. There is more information available (including a patch) at http://bugs.gentoo.org/show_bug.cgi?id=245283 My best regards, -- Ricardo I. Vieitez

FW: RE: How to determine whether the OS has the latest DST rules
by Olson, Arthur David (NIH/NCI) [E] Nov. 6, 2008

Nov. 6, 2008

I'm forwarding this message from Phil Guera, who sent it by way of a secure mail server. --ado Florence, I did some programming to read this information. Basically, the information is given in the area that Microsoft calls TZI. It's a complicated element to decipher, but if you give me the timezones you are interested in, I can give you screen shots of the interpretation of the registry binary data. I wrote this TimeZonesExplorer just before Microsoft added some historical capability to their registry's handling of timezones, and never did update it to read the historical data, but the way MS stores the info is based on the zone, current year, and subset of yearly historical data. Though their treatment of historical data doesn't go back in time very far like the TZ database does. I'm still running Windows XP pro, but I believe the registry is structured the same on Vista at this time. At any rate with the screen shots, you should be able to see the basics of how to make the binary data more human readable. It's just a matter of splitting the TZI info into parts and performing some hex math conversion to get to the actual information contained within it.

neverending Argentinian changes... Carmen de Patagones
by Mariano Absatz - El Baby Oct. 29, 2008

Oct. 29, 2008

The city of Carmen de Patagones (Provincia de Buenos Aires) http://en.wikipedia.org/wiki/Carmen_de_Patagones is "twin" to Viedma (Provincia de Río Negro) http://en.wikipedia.org/wiki/Viedma and many people in one city works or studies in the other... Since Río Negro is at UTC-3 and Buenos Aires at UTC-2, this has become more than a nuissance for people living in one city and working in the other one or, worse yet, having a different job in each or studying in one city and working in the other one... http://www.lanacion.com.ar/nota.asp?nota_id=1061607 http://www.lanueva.com/edicion_impresa/nota/29/10/2008/8at064.html The Intendente (Major?) of Carmen the Patagones asked the Governor of the Provincia de Buenos Aires to allow the city to adhere to UTC-3... apparently the Governor will reject it (and allow schools and public offices to change their timetables so as to coordinate them with the UTC-3 but calling it differently)... Except for the Provincial Bank (Banco de la Provincia de Buenos Aires) that must keep the same timetable in the whole Province... If this goes on like this (that is, Carmen de Patagones keeps the same timezone as the rest of the Province), then we're fine... otherwise... we'll have to split America/Argentina/Buenos_Aires into yet another timezone called America/Argentina/C_de_Patagones or something like that :-( I'll keep you posted... -- Mariano Absatz - "El Baby" baby(a)baby.com.ar www.clueless.com.ar -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Real programmers use: cat > a.out http://xkcd.com/378/ -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- * TagZilla 0.066 * http://tagzilla.mozdev.org

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 **** !

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?

Discrepancy between zone.tab ordering and northamerica details
by Eric Fischer Oct. 21, 2008

Oct. 21, 2008

We just ran into a bug at work where users in US Central Time were identified as being in America/Indiana/Knox instead of in America/Chicago because code was running through the list of time zones in zone.tab looking for the first one that matched the current GMT offset and DST state, and America/Indiana/Knox is currently observing CDT and ordered before America/Chicago. I hope this is actually a use that the file ordering is intended to support, but even if it isn't, the zone.tab file seems to be misleading for some Indiana towns. In particular, northamerica says that Petersburg is Eastern and Knox is Central, but zone.tab says that Petersburg is Central and Knox is Eastern. I've attached a patch to bring zone.tab into line with northamerica, at least for these two places. Eric

FW: Uncertain usage/scope of a possibly standard timezone name 'MEZ-1MSZ'
by Olson, Arthur David (NIH/NCI) [E] Oct. 21, 2008

Oct. 21, 2008

I'm forwarding this message from Stephen A. Hellberg, who is not on the time zone mailing list. Those of you who are on the list, please direct replies appropriately. --ado From: Stephen A Hellberg [mailto:HELLBES@uk.ibm.com] Sent: Wednesday, September 10, 2008 8:11 To: tz(a)lecserver.nci.nih.gov Subject: Uncertain usage/scope of a possibly standard timezone name 'MEZ-1MSZ' Hello, I'm not a member of the distribution list, although I believe my enquiry is covered by its scope, and I wonder whether you might be able to circulate my enquiry (and return any replies) as my own research has failed to identify an answer. I'm trying to service a request to recognise the standard timezone name of 'MEZ-1MSZ', but I've so far not found any documentation to support or define the scope if this is an acceptable POSIX TZ value and a standard timezone name. The suggestion has been made that MSZ is a widely(?) employed alias (in some region(s) of the Gernan speaking world?) for MESZ that is standardly defined for "Mitteleuropäische Sommerzeit" (GMT+0200); MEZ being an accepted acronym for "Mitteleuropäische Zeit". And, I whilst I can find instances for the use of the standard(?) 'MEZ-1MSZ-2' I have been unsuccessful in locating any equivalence for 'MEZ-1MSZ' itself. Is MSZ equivalent and a widely accepted acronym matching MESZ, and if so where and how typical is its use? How does it differ to the 'MEZ-1MSZ-2' standard? Can you/anyone advise on the practice of employing 'MEZ-1MSZ' as a POSIX TZ value or indeed how prevalent its use is, or in which region (likely related to honouring DST somewhere in the vicinity of Berlin?) and whether this is directly equivalent to other common/standard names, such as CET-1CEST? What should its Olson equivalent be? (Whilst my inconclusive researches have been more extensive, support for the above statement appears available readily here (amongst other places): http://www.timeanddate.com/library/abbreviations/timezones/eu/cet.html http://www.timeanddate.com/library/abbreviations/timezones/eu/cest.html http://www.all-acronyms.com/special/time_zone_acronyms_and_abbreviations.asp http://de.wikipedia.org/wiki/Zeitzone ) Thank you in anticipation, Stephen --- Stephen Hellberg Java L3 Service, IBM Hursley Email: hellbes(a)uk.ibm.com ________________________________________ Unless stated otherwise above: IBM United Kingdom Limited - Registered in England and Wales with number 741598.

Australia/Sydney TZ DST
by Geoff Capper Oct. 20, 2008

Oct. 20, 2008

Hi, I had a browse through your site and messages searching for the reason Java had not been updated with the changed DST dates for Eastern Australia, as Java indicates that they depend on results here. I noted a request for Australian DST information, but also noted that your database hasn't included recent changes to some of the Eastern seaboard DST dates. The Australia/Sydney zone in particular changed to DST on October 5th, and in future years the change will be on the 1st Sunday in October, and will end on the first Sunday in April. I believe the southern states are also in line with this. Further details are available from the NSW AG's Community Relations Unit site: http://www.lawlink.nsw.gov.au/Lawlink/cru/ll_cru.nsf/pages/cru_daylightsavi… Kind Regards, Geoff
