[tz] Aix question

Hi all,

Sorry for the off topic, but does anyone know the procedure for updating 
tz info on Aix? Google is not my friend today.

Thanks in advance. Great work, Paul.

[tz] Time, Clock, and Calendar Programming In C, by Eric S. Raymond

Eric S. Raymond has written an article about the history of the time.h
functions at http://www.catb.org/esr/time-programming/

From his blog post announcing it (http://esr.ibiblio.org/?p=6311):

> The C/UNIX library support for time and calendar programming is a nasty mess of historical contingency. I
have grown tired of having to re-learn its quirks every time I’ve had to deal with it, so I’m doing
something about that.
> 
> Announcing Time, Clock, and Calendar Programming In C, a document which attempts to chart the historical
clutter (so you can ignore it once you know why it’s there) and explain the mysteries.
> 
> What I’ve released is an 0.9 beta version. My hope is that it will rapidly attract some thoroughgoing
reviews so I can release a 1.0 in a week or so. More than that, I would welcome a subject matter expert as a collaborator.

When I saw it I thought it might be generally interesting to people who
subscribe to this list.

[tz] [tz-announce] 2014h release of tz code and data available

The 2014h release of the tz code and data is available.  It reflects the 
following changes, which were either circulated on the tz mailing list 
or are relatively minor technical or administrative changes:

   Changes affecting past time stamps

     America/Jamaica's 1974 spring-forward transition was Jan. 6, not 
Apr. 28.

     Shanks says Asia/Novokuznetsk switched from LMT (not "NMT") on 
1924-05-01,
     not 1920-01-06.  The old entry was based on a misinterpretation of 
Shanks.

     Some more zones have been turned into links, when they differed
     from existing zones only for older time stamps.  As usual,
     these changes affect UTC offsets in pre-1970 time stamps only.
     Their old contents have been moved to the 'backzone' file.
     The affected zones are: Africa/Blantyre, Africa/Bujumbura,
     Africa/Gaborone, Africa/Harare, Africa/Kigali, Africa/Lubumbashi,
     Africa/Lusaka, Africa/Maseru, and Africa/Mbabane.

   Changes affecting code

     zdump -V and -v now output gmtoff= values on all platforms,
     not merely on platforms defining TM_GMTOFF.

     The tz library's localtime and mktime functions now set tzname to a 
value
     appropriate for the requested time stamp, and zdump now uses this
     on platforms not defining TM_ZONE, fixing a 2014g regression.
     (Thanks to Tim Parenti for reporting the problem.)

     The tz library no longer sets tzname if localtime or mktime fails.

     zdump -c no longer mishandles transitions near year boundaries.
     (Thanks to Tim Parenti for reporting the problem.)

     An access to uninitalized data has been fixed.
     (Thanks to Jörg Richter for reporting the problem.)

     When THREAD_SAFE is defined, the code ports to the C11 memory model.
     A memory leak has been fixed if ALL_STATE and THREAD_SAFE are defined
     and two threads race to initialize data used by gmtime-like functions.
     (Thanks to Andy Heninger for reporting the problems.)

   Changes affecting build procedure

     'make check' now checks better for properly-sorted data.

   Changes affecting documentation and commentary

     zdump's gmtoff=N output is now documented, and its isdst=D output
     is now documented to possibly output D values other than 0 or 1.

     zdump -c's treatment of years is now documented to use the
     Gregorian calendar and Universal Time without leap seconds,
     and its behavior at cutoff boundaries is now documented better.
     (Thanks to Arthur David Olson and Tim Parenti for reporting the 
problems.)

     Programs are now documented to use the proleptic Gregorian calendar.
     (Thanks to Alan Barrett for the suggestion.)

     Fractional-second GMT offsets have been documented for civil time
     in 19th-century Chennai, Jakarta, and New York.

Here are links to the release files:

   ftp://ftp.iana.org/tz/releases/tzcode2014h.tar.gz
   ftp://ftp.iana.org/tz/releases/tzdata2014h.tar.gz

   http://www.iana.org/time-zones/repository/releases/tzcode2014h.tar.gz
   http://www.iana.org/time-zones/repository/releases/tzdata2014h.tar.gz

Each release file has a GPG signature, which can be retrieved by 
appending ".asc" to the above URLs.  Copies of these signatures are 
appended to this message.

As usual, links to the latest release files are here:

[tz] tz database

Hi,

I downloaded most recent tz data from http://www.iana.org/time-zones,

Time Zone Data v. 2014g (Released 2014-08-28)

tzdata2014g.tar.gz (278.2kb)

Time Zone Code v. 2014g (Released 2014-08-28)

tzcode2014g.tar.gz (174.0kb)

 

After reading the README file and other document, I understand that the gz is for compiling into unix commands that provide various timezone functions, am I correct?

 

If I m correct, does IANA provide a csv/xls download of tz with daylight saving time info for all cities in the world and delta download periodically?

 

 

Thanks & Regards,

Heather Zhang | Sabre | W: 682.605.2968 | B1 Flex

[tz] Republic of Belarus is considering time zone change due to Russia's change

Hi,

a local news site got a comment from  PR service of Belarussian National Standardization
Committee that government is currently deciding on the time zone change
to follow Russia. The decision is not yet made and I was unable to find
any other source or reference at any governmental site, which is,
unfortunately, typical.

[tz] Cayman Islands considering DST

The Cayman Islands are considering the use of daylight saving time for 
the first time.  The government is inviting public comment through 
October 30.  Arguments for DST include better synchronization with New 
York financial markets as well as stimulating tourism.  See:

Ministry of Financial Services, Commerce & Environment, Cayman Islands 
Government. Introduction of daylight savings time in the Cayman Islands.
