   While I have read all posts concerning setting the time as well as topics about the timezone, my puzzler is puzzled about setting the timezone on cooking.base CLI.

   Reader Digest version...

   I ran the command ntpdate pool.ntp.org to correct my system time. This brought about a time change difference of 5 hours my local time (USA-Chicago-CST) confirmed running the command date. I created /etc/TZ with UTC-5 per instructions on one post with no change. I have read I need to install glibc-locale 2.14.1 but I find it crazy I'll have to install 2000+ files just to be able to specify the correct timezone for my small, compact SliTaz base installation.

   Are there alternatives to my being able to use ntpdate to correct my system time and adjust for my timezone without having to install glibc-locale 2.14.1? If not I guess my alternative is to let the bios supply the time.. which of course will drift over time (pun intended).

   Thank you,
   Allen

   Individual files from cooking packages can be downloaded for manual installation to proper path.
   cook.slitaz.org
   Package: glibc-locale
   Click the files link
   Click the file name to download
   http://cook.slitaz.org/cooker.cgi?download=../wok/glibc-locale/taz/glibc-locale-2.14.1/fs/usr/share/zoneinfo/America/Chicago
   cp Chicago /usr/share/zoneinfo/America
echo America_Chicago > /etc/TZ
   reboot

   Alternative:
   Use an ftp capable browser (not midori) or client, go to http://ftp.cook.org <pkg name>/taz folder to download individual files

   Hi allen, mojo and kultex!

   First. The newest timezone files you'll find in the latest tzdata package (view files). Many files from this package has moved to the locale-** packages, and here you'll find the rest. Use ftp://cook.slitaz.org/tzdata to see all tzdata files.

   Download America/Chicago file using this link: http://cook.slitaz.org/cooker.cgi?download=../wok/tzdata/taz/tzdata-2014h/fs/usr/share/zoneinfo/posix/America/Chicago

   Make folder (as root user):
   mkdir -p /usr/share/zoneinfo/America

   Copy your Chicago file to the folder you create: /usr/share/zoneinfo/America

   Now you have timezone definition file: /usr/share/zoneinfo/America/Chicago

   Then put timezone to the system file (mojo's little mistake — not underscore but slash):
   echo "America/Chicago" > /etc/TZ

   And put timezone to environment variable (kultex's little mistake — there's no UTC-5 timezone file):
   export TZ="America/Chicago"

   Now try ntpdate.

   After reboot check that your TZ environment variable stores your value:
   

   printenv TZ
   America/Chicago

   I apologize for a delayed reply to mojo's post...

   @mojo

   I did notice I could dload individual timezone files but was overwhelmed by so many and how to install. I did as you suggested, dloading the Chicago timezone but did find the underscore a typo when only America showed in the timezone after running the command date. Replacing with America/Chicago worked perfect after rebooting and running ntpdate. Thank you!

   @kultex

   Yes I did find UTC- or + a number did change the timezone. I typo'd my first attempt, reason while it didn't work. Damn typo's. Thank you!

   @Aleksej

   I'm going to browse your links having mentioned newer timezone files. I am curious the difference it can make. Thank you!

   Let me know if any of you are ever in the Chicago area. I'll buy you a couple beers. :)

   Thanks to you all!

   Hi, allen!

   No. I'm from Ukraine (and my TZ is Europe/Kiev, by the way).

   If you curious about difference between tzdata versions, please read tzdata mailing list: http://mm.icann.org/pipermail/tz-announce/

   I want you to know that current tzdata version is 2014h. This "h" means eighth version in this year. I don't know version of tzdata included in our glibc (→ glibc-locale) package, but it dated as October 7, 2011. Everything is changing...

   @Aleksej

   Thank you for the link on the tzdata versions. In my quick look through I see what you are referring to. Interesting how all the information is collected toward updating SliTaz. Even more so what some might consider trivial...

   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.

   Thank you for all you do!

   allen,

   In your case there is no differences for America/Chicago, both files 3543 Bytes and have same md5sum.

   Something different for my country. Text from Wikipedia (Google Translate from Russian):

   September 20, 2011 Verkhovna Rada of Ukraine abolished the transition to winter time, keeping constant the summer, but October 18, 2011 reversed its decision.

   -
   Its all about Daylight saving time and actual versions.
