This bug was fixed in the package tzdata - 2021a-0ubuntu0.20.04 --------------- tzdata (2021a-0ubuntu0.20.04) focal; urgency=medium
* New upstream version (LP: #1913482), affecting the following future timestamp: - South Sudan changes from +03 to +02 on 2021-02-01 at 00:00. * Update ICU timezone data files which are utilized by php and update them to 2021a. -- Brian Murray <br...@ubuntu.com> Wed, 27 Jan 2021 13:32:53 -0800 ** Changed in: tzdata (Ubuntu Focal) Status: Fix Committed => Fix Released ** Changed in: tzdata (Ubuntu Focal) Status: Fix Committed => Fix Released -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to tzdata in Ubuntu. https://bugs.launchpad.net/bugs/1913482 Title: Update tzdata to version 2021a Status in tzdata package in Ubuntu: In Progress Status in tzdata source package in Xenial: Fix Committed Status in tzdata source package in Bionic: Fix Committed Status in tzdata source package in Focal: Fix Released Status in tzdata source package in Groovy: Fix Released Bug description: New upstream version affecting the following timestamp: - South Sudan changes from +03 to +02 on 2021-02-01 at 00:00. $region/$timezone = Africa/Juba 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 needs to be greped for in /usr/share/zoneinfo/). [For example: 'zdump -v Africa/Juba'.] This is compared to the same output after the updated package got installed. If those are different the verification is considered done. [Test Case for all releases] 1) zdump -v Africa/Juba | grep 2021 For releases with ICU timezone data verification is done using the following with dates before and after the change: [Test Case for releases >= 20.04 LTS] 1) sudo apt-get install python3-icu 2) python3 -c 'from datetime import datetime; from icu import ICUtzinfo, TimeZone; tz = ICUtzinfo(TimeZone.creat eTimeZone('Africa/Juba')); print(str(tz.utcoffset(datetime(2021, 2, 1))))' 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: [Test Case for releases <= 20.04 LTS] diff <(zdump -v America/Phoenix | cut -d' ' -f2-) <(zdump -v SystemV/MST7 | cut -d' ' -f2-) Nothing should be returned by the above command.
