The ICU timezone data has not yet been updated upstream so those changes will be included in a later SRU. Verification is done with 'zdump'. The first timezone that gets changed in the updated package is dumped with "zdump -v $region/$timezone_that_changed" (this needed to be greped for in /usr/share/zoneinfo/). [For example: "zdump -v Africa/Casablanca".] This is compared to the same output after the updated package got installed. If those are different the verification is considered done. $region/$timezone = Europe/Volgograd Additionally, an upstream update of tzdata removed the "old" SystemV timezones, so we should ensure that they are kept in Ubuntu 20.04 LTS and earlier releases. Subsequently, these should be checked for using the following: diff <(zdump -v America/Phoenix | cut -d' ' -f2-) <(zdump -v SystemV/MST7 | cut -d' ' -f2-) Nothing should be returned by the above command. [Original Description] https://www.iana.org/time-zones tzdata 2020f already exists, please update the package.
