Title: tzdata update keeps changing my timezone Status in tzdata package in Ubuntu: Fix Released Status in tzdata source package in Bionic: New Status in tzdata source package in Focal: New Status in tzdata source package in Jammy: New Status in tzdata package in Debian: Fix Released Bug description: [ Impact ] Users can select some time zones in debconf that the tzdata debconf script will replace on the next run. See "Original report" for more explanation. Either those time zones should not be selectable in debconf or they should not be replaced. [ Test Plan ] Select US/Central as time zone and run dpkg-reconfigure: ``` sudo ln -sf /usr/share/zoneinfo/US/Central /etc/localtime echo "US/Central" | sudo tee /etc/timezone sudo dpkg-reconfigure -fnoninteractive tzdata ``` The output of dpkg-reconfigure should say that the current default time zone is still US/Central. Besides this manual test, test_timezone_conversions is backported to check that there are no timezones which can be selected, but will be converted. [ Where problems could occur ] Besides added tests, the debconf part of tzdata is touched and could cause issues. The change does not touch the actual timezones. [ Original report ] 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.
