tzdata changes needed in Trisquel 4.5 (Ukrainian users will be affected after 29 Oct 2011)
Hello,
On September 20th, 2011 there were changes made to Ukrainian laws
concerning time zone. tzdata needs upgrade.
The time zone changes work okay in Debian, but do not work in Trisquel.
Compare outputs of 'date'. This looks like the right one (FET, both
21:57):
# echo $(lsb_release -ircs)
Debian 5.0.9 lenny
# aptitude show tzdata | egrep '^Version:'
Version: 2011k-0lenny1
# (export TZ='Europe/Kiev'; date --date='2011-10-29 18:57 UTC')
Sat Oct 29 21:57:00 FET 2011
# (export TZ='Europe/Kiev'; date --date='2011-10-30 18:57 UTC')
Sun Oct 30 21:57:00 FET 2011
This is not right (tried it *after* 'aptitude upgrade tzdata'):
$ echo $(lsb_release -ircs)
Trisquel 4.5 slaine
$ aptitude show tzdata | egrep '^Version:'
Version: 2011g-0ubuntu0.10.10
$ (export TZ='Europe/Kiev'; date --date='2011-10-29 18:57 UTC')
Sat Oct 29 21:57:00 EEST 2011
$ (export TZ='Europe/Kiev'; date --date='2011-10-30 18:57 UTC')
Sun Oct 30 20:57:00 EET 2011
Where is the right place to file this bug?

Hello,
I suspect that this change had already being made in the database
because it reflects reality in Debian/lenny updates, for example (I
specified that in my original post). Debian updates have "2011k-..."
version of the tz database.
There is an old ("2011g-...") version of the tz database in
Trisquel/slaine. That's why I'm writing to the Trisquel mail list.
Michael.

2011j-0ubuntu0.10.10 is available in Trisquel Slaine: http://packages.trisquel.info/slaine-updates/tzdata
Don't you have slaine-update in /etc/apt/sources.list? You can check (and enable) it from the "Update" tab of the "Software sources" in the "System/Administration menu" (translation from French, the labels may be different) too.
Hello,
This is what is in my sources.list:
$ lst='/etc/apt/sources.list'; ls -ld "$lst"
-rw-r--r-- 1 root root 815 2011-08-13 09:15 /etc/apt/sources.list
$
$ fgrep ' slaine-updates ' "$lst"deb
http://ftp.rediris.es/mirror/Trisquel/packages/ slaine-updates main
deb-src http://ftp.rediris.es/mirror/Trisquel/packages/ slaine-updates
main
Are those wrong records?

I've just tried it again. New tzdata version is installed, but the
problem persists:
$ echo $(lsb_release -ircs)
Trisquel 4.5 slaine
$ aptitude show tzdata | egrep '^Version:'
Version: 2011j-0ubuntu0.10.10
$ (export TZ='Europe/Kiev'; date --date='2011-10-29 18:57 UTC')
Sat Oct 29 21:57:00 EEST 2011
$ (export TZ='Europe/Kiev'; date --date='2011-10-30 18:57 UTC')
Sun Oct 30 20:57:00 EET 2011
The issue is (probably) solved in "2011k", but it doesn't seem to be in
Trisquel slaine updates.

I do not know why this version has not reached Trisquel yet. It certainly will. Anyway, if you want a quick fix, you can download and install the package from Maverick's update repository (Trisquel does not modify this package): http://packages.ubuntu.com/maverick-updates/all/tzdata/download
By the way, just out of curiosity, why sticking to Trisquel 4.5 Slaine (which is not LTS) when Trisquel 5.0 Dagda is available and extremely similar? An allergy to Firefox 7 maybe?

Thanks, I'll consider it.
There're possible other wirkarounds as well, but what concerns me are
possible problems for other Ukraininan slaine users. That's why I asked
about seamless update solution for 4.5.

The reason is quite simple. For now I don't have time to solve possible
problems during upgrade, that's why I'm still sticking with slaine (it's
still supported till March 2012, right?).
In particular, I use full HDD encryption on my laptop (lvm, cryptsetup,
lvm again, fs/swap). In case the upgrade breaks my system, I will need
significant amount of time to recover. Time is critical for me these
days. That's why I would prefer to wait for several months before I
taste Firefox 7 or something :)

Hello again,
There are news accordong to which it seems that Ukrainian law makers
gave a step back and cancelled[1] the time zone changes I was writing
about. This means that 30 Oct 2011 there WILL be usual time zone change
from EEST (UTC+3) to EET (UTC+2). If so, then the current tzdata in
Trisquel/slaine is correct. To check it on your system, try ths:
$ (TZ='Europe/Kiev'; date --date='2011-10-29 18:57 UTC')
Sat Oct 29 21:57:00 EEST 2011
$ (export TZ='Europe/Kiev'; date --date='2011-10-30 18:57 UTC')
Sun Oct 30 20:57:00 EET 2011
If it displays as above ("29 21:57:00 EEST" and "20:57:00 EET"), then
you machine should do the timeshift seamlessly.
I would recommend every user who uses 'Europe/Kiev' timezone to check
this few days before the time shift AND after each upgrade [of tzdata]
during a month or two because AFAIU there were changes made into the
original tzdata already, so you can unintentionally unpgrade to wrong
time zone setting for Ukraine (depends on what tzdata version is used in
your OS distribution).
