Please run a test for me (it takes only minutes)

Posted on May 9, 2008 by Lennart Regebro

In my post on Python and time zones I mentioned that I hadn’t tried this on Windows yet. But now I have, and I have painstakingly and with help from several Mac OS X users come up with something that may be a way of getting the time zone information reliably on both Linux, Mac OS X and Windows. But of course, I’m not sure.

So therefore, I’d like to ask you, dear reader, to make a quick test for me. Especially if you live in a strange timezone, or have an unusual os, or weird time zone setup, or anything else.

The steps are as follows (the svn line gets cut off, but you can still copy and paste it):

svn co http://www.plone4artists.org/svn/projects/Plone4ArtistsCalendar/tztest/trunk tztest
cd tztest
python tztest/__init__.py

Whatever the output is, paste it as a comment on this blog post. If you get an unexpected result, i.e. and error, or if the time zone printed is wrong, then *please* leave a correct email address when you fill in the comment.

    Wow. Ubuntu 8.04, and *None* of the techniques worked.
    There is no /etc/timezone, although there should be, and for some reason /etc/localtime is not a copy of /usr/share/zoneinfo/US/Eastern, which it should be.

    If it’s impossible even on Ubuntu 8.04 to figure out your correct timezone in a reliable manner I think it’s time to give up for me. :) This isn’t going to work.

    Ubuntu 8.04 geives me this:

    [tztest 3.1]
    No reliable timezone found. Using time.tzinfo.
    The time zone name is: CEST

    And for the record:

    $ ls -al /etc/*time*
    -rw-r–r– 1 root root 45 2008-05-09 17:19 /etc/adjtime
    -rw-r–r– 1 root root 1074 2007-10-21 10:01 /etc/localtime
    -rw-r–r– 1 root root 13 2008-03-30 13:51 /etc/timezone
    $ cat /etc/timezone
    User defined
    $

    After setting the timezone (hadn’t I done that already?):

    $ ls -al /etc/timezone
    -rw-r–r– 1 root root 45 2008-05-09 17:19 /etc/adjtime
    lrwxrwxrwx 1 root root 36 2008-05-11 08:38 /etc/localtime -> /usr/share/zoneinfo/Europe/Amsterdam
    -rw-r–r– 1 root root 17 2008-05-11 08:38 /etc/timezone
    $ cat /etc/timezone
    Europe/Amsterdam
    $

    Your script now does this:

    -rw-r–r– 1 root root 17 2008-04-25 22:56 /etc/timezone
    $ cat /etc/timezone
    Europe/Amsterdam
    $

    So while /etc/localtime is not a symlink to /usr/share/…, the correct timezone is stored in /etc/timezone.

  63. Lennart Regebro, on May 11th, 2008 at 8:10 Said:

    Well, you time zone was configured enough for /etc/localtime to contain CET/CEST. But somehow the time zone was not configured based on the zoneinfo data.

    That this can happen, and evidently happens quite often, means that it’s going to be hard to get a reliable zoneinfo time zone from the Ubuntu configuration.
