Bug Description

Binary package hint: tzdata

Other than the fact that Chicago, Illinois is in US Central Timezone, I have no relationship to Chicago. I am not in Chicago. I do not want to be in Chicago. I am in the Central Timezone. I am physically closer to other cities mentioned in tzdata. Selecting America/Chicago versus US/Central is not easier for me nor is it more intuitive. I understand that the upstream tzdata package goes a long way in documenting all of the weirdness associated with timezones and different localities' treatment of timezones and daylight "savings" time. However, from an end-user perspective, the distribution should place no special importance or preference on one timezone specification or another. Likewise, if a user chooses a timezone, the system should never change it.

To reproduce the issue:

# Manually select US/Central
me@ubuntu:~$ sudo dpkg-reconfigure tzdata
[sudo] password for me:

Current default time zone: 'US/Central'
Local time is now: Wed Apr 27 16:05:02 CDT 2011.
Universal Time is now: Wed Apr 27 21:05:02 UTC 2011.

# Validation that selection was accepted
me@ubuntu:~$ cat /etc/timezone
US/Central

me@ubuntu:~$ md5sum /etc/localtime /usr/share/zoneinfo/US/Central
6540624294b1193e22ed7a15692f2de7 /etc/localtime
6540624294b1193e22ed7a15692f2de7 /usr/share/zoneinfo/US/Central

me@ubuntu:~$ debconf-show tzdata

Also, it breaks my system clock which keeps jumping to 2 hours ahead.

Is there any way we could see about having this package patched by an Ubuntu maintainer?

Based on reading over the open bugs associated with tzdata on Debian's bug tracker, this report and several other reports for the same undesirable behavior have languished from anywhere from 6 months to several years without a single response from the maintainer(s).

I don't know if that indicates a lack of concern about the issue or that the package itself isn't being actively maintained beyond database updates but in either case it seems to me that a user shouldn't have to constantly reset /etc/timezone in order to prevent it from being updated to a technically correct although undesirable value.
