Time format error in Olson TZ rules for Asia
by tojo.mathew＠nokia.com April 27, 2010

April 27, 2010

Hello, We have noticed a possible error in Jordan rule. It uses time value 24:00 in recent updates of Olson rule files. Rule Jordan 2002 max - Mar lastThu 24:00 1:00 S As per RFC 3339,( Clause :5.6. Internet Date/Time Format) it recommends time format from 00-23 for hours. (http://www.ietf.org/rfc/rfc3339.txt ) This implies Jordan rule may need to be changed to: Rule Jordan 2002 max - Mar lastFri 0:00 1:00 S Please check this and update in subsequent releases if found appropriate. Regards, Tojo Mathew Senior Engineer,Application S/W Nokia

Time zone file naming scheme
by Stephen Colebourne April 27, 2010

April 27, 2010

As spec lead of JSR-310, the Java effort to enhance dates and times, I'm encoding TZDB data. In order to represent the different versions of the data, I'm using the tzdb naming scheme or year followed by letter, eg. 2010i. This version number is sorted alphabetically. Obviously, it is possible that there might be more than 26 releases of the data in one year. In order to maintain the alphabetical sort order, I'd like this list to determine a strategy for the unlikely event that this situation occurs. For example: 2010a 2010z 2010za 2010zb If the list does not arrange a strategy (and define it in the theory document), then JSR-310, or future maintainers, will have to make up our own approach for numbering the 27th and onwards releases. Opinions? thanks Stephen

user-friendly time zone list
by Douglass Davis April 20, 2010

April 20, 2010

Hello All, I am attempting to find a user-friendly list of time zones for users to select their current time zone. It would have common names that timezones are referred to, such as Eastern Time (US and Canada), and/or city names. This list should map the text to a time zone name such as "America/New_York." It would also remove multiple listings for what the user thinks of as the same time zone. Does any one know of such a list? If not, I would like to create one. One thing that perhaps would help is if I could group many timezones by if they are implemented exactly the same way in 2010. This would make it easy to remove multiple listings for the "same" time zone. Also, if there are any time zones that are strictly there for historical purposes, I would like to not have them in the list. I will put this list in the public domain if any other application developers want to use it. Please let me know if you have any suggestions as far as where I could find this list, or how I could create it. Thanks. -- Douglass Davis Applications Developer UNC - General Administration

(There are no plans to add an America/Brasilia alias. If it's any consolation, the United States is in a similar boat--the time zone I'm in is named America/New_York rather than America/Washington_DC. --ado From: Leonardo Ferreira Fontenelle [mailto:leonardof@gnome.org] Sent: Sunday, April 18, 2010 10:36 To: tz(a)lecserver.nci.nih.gov Subject: Creating an alias to America/Sao_Paulo I am a GNOME trasnlator, and I received an e-mail from an user about the choice of the São Paulo city as the name for the corresponding time zone. I understand this is the most populous city, but he made a good point: in Brazil we call this time zone "Brasília time". Brasília has been our country capital for 50 years, since the government finished building it for this specific purpose.

tzdata question
by bobgerman＠bobgerman.com April 14, 2010

April 14, 2010

Hello, I hope this is the right place for this question. A coworker suggested filing a bug report, but I'm not confident enough in what I'm seeing to do so. I recently updated two servers from CentOS 5.2 to 5.4. In the process, of course, the tzdata package was updated. Shortly after updating, my boss began barking about a server with the wrong timezone showing up in our logging. He's very uptight about that sort of thing. We log everything with UTC religiously because we have servers all over the planet. Further investigation revealed that on these two particular servers, which had been updated with CentOS 5.4 (and the tzdata package), we could NOT change the time by the usual means (rm /etc/localtime; ln -s /usr/share/zoneinfo/UTC /etc/localtime). This works everywhere else in our datacenters, so we were confused. Upon looking closer, it appears the UTC file installed by the latest tzdata package is not a UTC file. Running strings on it reveals EST5EDT. I don't know if this is a problem at the source, or a packaging problem somewhere along the stream. I'm sending it to this email address because this is what I found in the README for the tzdata package. Please feel free to correct me in any way that will help me stop my boss from barking, as this is every information technologist's duty in life. Thank you for your brain cycles.

The file... ftp://elsie.nci.nih.gov/pub/tzdata2010h.tar.gz ...is now available; this reflects the changes circulated last week on the time zone mailing list. I believe we're now update with this year's changes. There's still work to do on past changes in Ontario, Canada and Taipei. There are also questions about just what happened on the Mexico side of the U.S.-Mexico border this year. And there's the West Bank to be examined. --ado

[somehow OT] "undoing" manual tzdata compilation on a Mac
by Mariano Absatz - El Baby April 2, 2010

April 2, 2010

Hi, I know Argentina has a long history of doing last minute changes about our timezones including inter-provincial anarchy. However, tzdata is easy enough to quickly adapt to this changes, and if you're somehow savvy, it is quite easy to fix things on your own. Last October, Argentina decided not to apply DST this (Southern) summer on the last minute and this was reflexed on tzdata2009p published on October 26th. Since Apple didn't immediately made this changes, knowing that OS X is actually running on top of some kind of BSD and actually finding zic and /usr/share/zoneinfo in it, I volunteered "fixing" a friend's macbook pro. I simply compiled the southamerica file from tzdata2009p and that was it... right? wrong! This actually made the mac go somehow crazy since it also uses some ICU files which I don't know how to handle. My friend ended up using Chile's time during the summer and Uruguay's time after Uruguay's DST period ended. Since a week ago the non-existent DST for Argentina would have ended, I told him to try again Argentina's time but it keeps being inconsistent. Another mac he has at home has now the correct time. Does anyone know how to restore the original OS X tzdata files without reinstalling the OS? I know nothing about its packaging system... Mac users seem to rely on "Apple update" service but I probably f##k'd it up when I overwrote some files under /usr/share/zoneinfo. Any help (or links to better places) will be greatly appreciated. -- Mariano Absatz - "El Baby" baby(a)baby.com.ar www.clueless.com.ar -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- I haven't lost my mind, I have it backed up on tape somewhere. -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- * TagZilla 0.066 * http://tagzilla.mozdev.org

FW: Questions about tzdata implementations
by Olson, Arthur David (NIH/NCI) [E] April 1, 2010

April 1, 2010

I'm forwarding this message from Chad Eberle, who is not on the time zone mailing list. Those of you who are on the list, please direct replies appropriately. --ado -----Original Message----- From: Chad Eberle [mailto:ceberle@co.pierce.wa.us] Sent: Monday, March 29, 2010 1:15 To: tz(a)lecserver.nci.nih.gov Subject: Questions about tzdata implementations I apologize if this isn't the right place for this question, but would appreciate any help with tracking down the answer to these questions. Background: We have Java web services that send back date/time values with GMT offsets adjusted for DST following historical rules that match what I see in the northamerica file for America/Los_Angeles. Our client code is largely JavaScript, and depending on the operating system, will sometimes be incongruous about when DST starts or ends (dates before 2007 on Windows and before 1950. As one can imagine, this has caused a few problems. I can't seem to find any solution for the JavaScript end, so I was planning on writing one myself (if anyone knows of a solution, I'd appreciate any pointers). My questions: 1) Is there some reference implementation for the algorithm that selects the correct rule for a given date? 2) For the general US rules, there is a rule that says DST started in 1945 on Aug 14 at 23:00; however, my tests in Java indicate that DST was observed from Feb 9 1942 through Sep 30 1945, continuously. The latter matches the historical information I've found. Is this rule superfluous? Again, any tips would be appreciated. --Chad Eberle
