tzcode2012i and tzdata2012i available
by Paul Eggert Nov. 3, 2012

Nov. 3, 2012

The 2012i release of the tz code and data is available. It reflects the following changes recently circulated on the tz mailing list: Cuba switches from DST tomorrow at 01:00. (Thanks to Steffen Thorsen.) Linker flags can now be specified via LDFLAGS. AWK now defaults to 'awk', not 'nawk'. The shell in tzselect now defaults to /bin/bash, but this can be overridden by specifying KSHELL. The main web page now mentions the unofficial github repository. (Thanks to Mike Frysinger.) Tarball signatures can now be built by running 'make signatures'. There are also new makefile rules 'tarballs', 'check_public', and separate makefile rules for each tarball and signature file. A few makefile rules are now more portable to strict POSIX. The main web page now lists the canonical IANA URL. Here are links to the release files: http://www.iana.org/time-zones/repository/releases/tzcode2012i.tar.gz http://www.iana.org/time-zones/repository/releases/tzdata2012i.tar.gz ftp://ftp.iana.org/tz/releases/tzcode2012i.tar.gz ftp://ftp.iana.org/tz/releases/tzdata2012i.tar.gz Each release file has a GPG signature, which can be retrieved by appending ".sign" to the above URLs.

Australia AEDT/EDT
by Steven Weiss Nov. 1, 2012

Nov. 1, 2012

Hi, I've been testing the timezone abbreviation and it seems to be incorrect for the current DST The abbreviation is giving me a EST instead of the expected EDT. I'm aware from your list there is a lot of discussion around EST/EDT vs AEST/AEDT. This is not the issue for me. either/or would be fine. Rather it appears that it should currently EDT/AEDT. I've downloaded the latest data and code as per the README. Regards Steven Weiss Cape Town South Africa

Australian Timezone Abreviations - Next step
by Shaun Bouckaert Oct. 27, 2012

Oct. 27, 2012

After taking some time off from this issue, I've considered the next logical step to be contacting the relevant government departments in charge of the timezone legislation in each state. As a Queenslander I will start with the Queensland Attorney-General, as the timezone legislation falls under his responsibility. I honestly believe that the only argument for the status quo on this issue is that it's been this way for a long time. I have previously presented many good arguments as to why it needs to be updated to reflect what is widely used amongst government and private organisations across the country, and what is presented by the federal government on this page http://australia.gov.au/about-australia/our-country/time Hopefully, with responses from the relevant state departments, this issue can be resolved and put to bed.
